Eight-year-old Bruce Wayne falls into a cave, where he encounters a swarm of bats. Having developed a fear of bats, he urges his parents to leave the opera, which features bat-like creatures. Outside the theater, they are mugged by Joe Chill, who proceeds to kill the parents. Although Chill is later arrested, Bruce blames himself for his parents' murders.

Years later, Bruce returns to Gotham City from Princeton University, intent on killing Chill, whose prison sentence is being suspended in exchange for testifying against mobster Carmine Falcone. Before he can act, a woman posing as a reporter kills Chill for Falcone. Bruce tells his childhood friend Rachel Dawes about his plan, and she expresses disgust for his disregard for justice. Bruce confronts Falcone, who tells him that he is ignorant of the nature of crime, so Bruce decides to travel the world to understand the criminal mind. After nearly seven years, he is detained for theft in a Bhutanese prison, where he meets Henri Ducard. Ducard invites Bruce to join an elite vigilante group, the League of Shadows, led by Ra's al Ghul. Bruce is freed and travels to a mountaintop to begin his training with the League. Bruce overcomes his childhood fear of bats in the process. When he is ordered to execute a criminal and learns of Ra's intention to destroy Gotham, he refuses and escapes by lighting the League's temple on fire, killing Ra's in the process. Bruce rescues an unconscious Ducard from the wreckage and leaves him at a village.

Bruce returns to a Gotham City ruled by Falcone, and plots his war against the city's corrupt system. He seeks the help of Rachel, now an assistant district attorney, and police sergeant Jim Gordon, who consoled him after his parents' murder. After reestablishing his connections to Wayne Enterprises (now run by William Earle) Bruce acquires, with the help of former board member Lucius Fox, a prototype armored car and an experimental armored suit. In his first night, he disrupts a drug shipment, and leaves Falcone tied to a searchlight, forming a makeshift Bat-Signal. He also disrupts an assassination attempt on Rachel, leaving her with evidence against a judge on Falcone's payroll. While investigating the drugs in the shipment, Batman is stunned by psychopharmacologist Dr. Jonathan Crane, who sprays him with a powerful hallucinogen. Bruce's butler Alfred Pennyworth rescues Bruce, who uses an anti-toxin developed by Fox to save him. Crane later poisons Rachel after showing her that the toxin, which is harmful in vapor form, is being piped into the city water supply. Batman saves her and attacks Crane with his own poison. When the police arrive at Arkham to arrest Crane, Batman escapes with Rachel in the Batmobile. After administering the antidote to her in the Batcave, he gives her two vials of it for Gordon – one for inoculating himself and the other for mass-production.

Later, in Wayne Manor, Bruce is confronted at his birthday celebration by a group of League of Shadows ninjas led by Ducard, who reveals himself to be the real Ra's al Ghul, and that the man killed earlier was a decoy. Ra's, who had been conspiring with Crane the entire time, plans to destroy Gotham by distributing the toxin via the city's water supply, and vaporizing it with a microwave-emitter stolen from Wayne Enterprises. Bruce dismisses his guests by insulting them while pretending to be drunk, and fights briefly with Ra's while the League set fire to the Manor. At the last minute, Bruce escapes the inferno with Alfred's help. Batman arrives at the Narrows section of Gotham to aid the police in battling psychotic criminals, including Crane, now calling himself "Scarecrow", whom the League set free. Rachel is briefly confronted by Crane, but quickly wards him off with a taser before being chased by more inmates. After saving her, Batman reveals his identity to her, and leaves Gordon in control of the Batmobile to stop the elevated train used to transport the weapon to the city's central water-hub. Batman battles Ra's aboard the train, then escapes just as Gordon topples the elevated line using the Batmobile's missiles, leaving Ra's to crash to the ground and perish in the explosion.

Following the battle, Batman becomes a public hero. Bruce gains control of Wayne Enterprises and installs Fox as the new CEO, firing Earle. However, he is unable to hold onto Rachel, who cannot reconcile her love for Bruce with his dual life as Batman. Newly Lieutenant Gordon unveils a Bat-Signal for Batman. Gordon mentions that they will have their hands full finding all of the psychopaths released from Arkham by Ra's, and in particular notes a criminal who also has "a taste for the theatrical" and leaves Joker playing cards at all of his crime scenes. Batman promises to investigate it and leaves.

The movie begins with a gang of men with clown masks breaking into the bank where the mob has a large portion of their money stashed. It begins with five clowns, each getting a cut of the spoils. They suggest that a sixth member of the gang, who did the planning but sat out the robbery, doesn't deserve a cut. As the robbery goes on, the clowns begin to kill each other in order to get a larger cut, until a school bus crashes through the wall of the bank, killing another clown. A mob bank manager, who was himself shot with an automatic weapon after he tried to take out the clowns with a shotgun, tells the remaining clown that he doesn't know who he is dealing with. The clown kneels down and tells the mobster that he believe that, "Whatever doesn't kill you simply makes you...stranger..." then removes his mask to reveal that he is The Joker. Joker puts a grenade into the mobster's mouth and boards the bus, leaving a string attached to the pin. The bus pulls out with all of the bank's cash and the pins pops out. It is just a gas grenade. The Joker joins a long line of school buses leaving the scene as the police arrive.

Gotham is then seen at night with criminals afraid to commit crimes under the watchful sign of the batsignal projected onto the clouds. We see Lt. James Gordon manning the batsignal, waiting for Batman with Det. Ramirez, who asks if he's coming. Gordon explains that it is okay if he is not, hoping that he is busy elsewhere.

Meanwhile, in a parking garage, Scarecrow is negotiating with the Russian mob members over the sale of some of his paranoia-inducing drugs. The sale is interrupted when some of Gotham's citizens dressed as Batmen wanna-be's begin shooting at the men. As he gases one of the fake Batmen with his mind-altering drugs from his cuff, the Scarecrow notes that they are not the real Batman, because Batman would never use a gun. Suddenly the Batmobile/tumble crashes through a barricade and Scarecrow notes, "that's more like it!" The Batmobile fires rockets into a nearby office causing the mobsters to begin to flee. The real Batman arrives on the scene and bends the rifle of one of the wanna-be Batmen before knocking him out.

The Russian mob leader sends his large dogs to attack the batmen, and as Batman saves them he takes the dogs out after being badly bitten in the arm. The Scarecrow attempts to flee in a white van but Batman jumps onto the van and begins cutting into the side with his gauntlets. Scarecrow swerves into a support which sends Batman to the ground. As Scarecrow gets away down a spiraling passageway, Batman leaps onto the roof of his van, smashing it to a halt. He leaves the fake Batmen and the Scarecrow along with some of the mobsters tied up together for the police to eventually round up.

Gordon arrives at the bank the Joker held up earlier with Ramirez who shows him the Joker's picture from a security camera. Batman arrives to inspect the scene, noting that they have irradiated the drug money to make it easier to trace. When Gordon asks him if the Joker is a threat, Batman informs him that he cannot worry about one man when there is an entire mob to bring down.

The next day, as Bruce Wayne stitches himself up from the dog bite, Alfred offers his concerns, warning Bruce to 'know his limits'. He notices Bruce keeping a close watch on Harvey Dent via some computer screens, as Bruce is trying to decide whether or not Dent can be trusted. Alread wonders if he is really spying on the relationship that Rachel Dawes has developed with Harvey Dent.

Harvey Dent arrives in court to join Rachel Dawes in prosecuting a man named Salvatore Maroni, the alleged new leader of Gotham's mob. One of Maroni's men takes the fall in court, and attempts to shoot Dent from the witness stand. The gun doesn't go off and Dent punches the man before he is hauled off to jail. Maroni is eventually set free, to the dismay of Dent.

Dent meets Lt. Gordon, and after a short exchange of words, they both express their distrust for those that are working in each other's offices. Harvey interrogates Gordon over his involvement with the Batman and Harvey tells him he wants to meet him. Gordon requests search warrants for five banks that are believed to be holding the remainder of the mobs money. Dent agrees to back Gordon's search warrants, forming a tenuous trust with the honest Gordon, who in turn hails Dent as Gothams "White Knight."

Lucious Fox holds a board meeting at Wayne Enterprises, negotiating an joint venturel with Lau, the head of Lau Security Investments, based in Hong Kong. After the meeting with Lau, Wayne expresses his reservations with Lucius Fox about Lau's business operation, apparently illegal based on their profits. After agreeing to cancel the deal, Wayne asks Fox for a new suit. He explains that he needs to be lighter, and faster, in case he runs into any more guard dogs.

That night, Harvey dines out with Rachel. Harvey tells Rachel he had to make a reservation weeks earlier, and even then needed to exercised his influence to get a table at the very fashionable restaurant. Bruce and his date, a Russian prima ballerina, encounter Rachel and Harvey. Bruce has them pull a table together so they can dine together, informing Harvey that he owns the restaurant. At first, Bruce seems jealous and threatened by Harvey, based on the fact that he is dating his own love interest, but Harvey explains how he supports the work of Batman and appreciates his help. Bruce changes his tune and informs Harvey that he intends to throw a massive fund-raiser for him.

Meanwhile, all of the top mob members are having a meeting. Because of their inside sources in the police, they were aware that the banks that their money was stashed in were going to be searched. Lau appears to them on a television monitor from his plane on his way back to Hong Kong. He informs the mob that all of their money has already been moved to a single secure location, just as Lt. Gordon and company are searching the banks, finding nothing but the irradiated trace money. When the Russian expresses concern over the man with the 'clown" makeup stealing $68 million from one of their banks, Maroni dismisses him as nothing but an annoyance.

The Joker enters in the room, and after killing a hostile mob member by way of a 'magic trick', sits down and talks with the mob about how pathetic they've become since Batman came around. He tells them their one solution is to 'Kill the Batman', and offers to do so for half the mobs money. he warns them about Lau, saying he knows a squealer when he sees one, causing Lau to promptly turn off his monitor. The mob laughs, and as one of the mob members, Gambol, rises from his seat and threatens the Joker, the Joker opens his coat, exposing grenades. Gambol tells the Joker that he's putting a price out on his head. The Joker tells the mob that when they plan to take things a little more seriously, give him a call, and presents them with 'his card', a joker playing card. And with that, he exits. But not before warning that Batman will be coming for Lau.

Harvey Dent, with Gordon, lights the batsignal to meet with Batman, who appears. As Dent and Gordon blame one another for the money's disappearance due to leaks from corrupt officers in the other's departments, they explain to Batman that they need Lau back, realizing that Batman is under no one's jurisdiction. They want to make him talk, and give up all the mob members' names. Batman agrees and disappears.

Fox shows Wayne his new suit, and Wayne begins planning an impromptu trip to Hong Kong. Fox will accompany him, making it look like the only reason for his visit was to cancel the negotiations with Lau's company.

Gambol is playing pool with some of his associates until one of them informs him that someone has killed the Joker, and has the body. The body is brought in covered in a bag, and as Gambol is about to pay, the Joker rises up and holds a knife to his face while his men who had said that they killed him hold guns to his associates' heads. The Joker tells a story about how he got his scars from his father, and then kills Gambol. He offers the three surviving associates an opportunity to join his gang, but he has only one opening! He leave the three with the halves of a broken, sharp pool stick and no choice but to fight each other for their lives.

Meanwhile, Fox arrives in Hong Kong to meet with Lau. He checks in his mobile phone at the front desk at Lau's building, as there are no cell phones allowed on the premises. Fox meets with Lau, and informs him of Wayne Enterprises' plans to cancel negotiations with his company. However, he secretly keeps one cell phone in his pocket, which has been adapted to produce a sonar map of the surrounding area. Upon leaving the building, he does not pick up the phone he dropped off, and he produces the map of the building to Bruce Wayne. That night, the phone that Fox left at the front desk emits a high frequency that shuts down all power in the building. Batman crashes in through a window in Lau's office, and after disabling some guards, grabs Lau and escapes by sending a ballon attached to a cable to a plane he has chartered flying over Lau's building.

Back in Gotham, Lau is interrogated by Rachel with Dent and Gordon looking on. Rachel presses him to give them the money Lau has taken, but Lau will not give in. After she threatens to have him moved to the County lock-up, Lau tells her that he can give them the names of the mobsters and their pooled investments. Dent then realizes that they will have the leverage they need in a RICO case of conspiracy to link all of the mob members together. Gordon decides to keep Lau in his holding cell at the Major Case Unit building and Lau agrees to cooperate with the police, and give the names of the mob members.

Gordon appears at Moroni's restaurant as the police rush in to arrest all of the mob members in attendance. As all of the mob members that Lau informed the police of get rounded up for arraignment Judge Surrillo finds a Joker card in the middle of the stack of conviction papers. Dent gives a televised impromptu interview denying Batman's involvement while expressing gratitude for the police work in bringing the mob members to justice.

Dent, Gordon, and Commissioner Loeb meet with the mayor to tell him that Dent's rash indictment of the mob members will give them mayor clean streets for 18 months. The mayor informs Dent that his brash actions will bring down the full might of Gotham's underworld and corrupt citizens solely upon him. When the mayor asks if Dent is ready to be the city's target the dead body of a Batman wanna-be hanging by a noose slams against the mayor's window dressed up in a Batman suit, with makeup on his mouth like the Joker's and with a Joker card pinned to him reading 'Will the real Batman please stand up?'. Bruce and Alfred watch on as a video tape is played on the news of the Joker tormenting the wanna-be before killing him. He then promises that until Batman takes off his mask and shows everyone who he really is, people will die every day.

As Harvey Dent's fund-raiser at Wayne at penthouse gets underway, Rachel and a nervous Dent arrive and mingle. Wayne arrives with three models via helicopter and seeks out Harvey, whom he applauds and throws his full support behind claiming, "I believe in Harvey Dent." Minutes later, Rachel meets with Bruce on the balcony upset that Bruce is making fun at Dent but Bruce tells her that he truly believes in Harvey and that he could be the White Knight that will allow him to hang up his mantle as Batman so they can be together. Dent joins them to thank Bruce and retrieve Rachel.

Meanwhile Gordon discovers that there are 3 traces of DNA on the Joker card, from Commissioner Loeb, Harvey Dent, and Judge Surrillo, the Judge that is trying all of the mob members and found the card among the paperwork. Gordon takes this as a threat on their lives, and begins preparations to protect them. In the case of the Judge and Commissioner Loeb, however, this fails. The Judge's car blows up when the police arrive to take her into protective custody, and Commissioner Loeb dies of severe poisoning from his liquor bottle before Gordon can stop him from drinking.

Dent takes Rachel aside to ask her to marry him, but she is torn and cannot give him an answer. Bruce subdues Dent and locks him in a closet while Rachel watches in shock. Bruce tells Rachel that they (the Joker and his goons) have come for Harvey and to stay hidden from sight.

The Joker and his goons burst in telling the guests that they are tonight's 'entertainment." The Joker scans the room seeking out Harvey Dent when Rachel steps forward and says, "Enough." He grabs her and pulls a knife on her telling her a different version of the story about how he got his scars, claiming that his wife was scarred in the same way by loan sharks and that he took a razor to himself to "make her smile," but that she left him over it. Rachel kicks him away and he comes after her saying that he "likes them with a little fight in them," when Batman shows up and sends him reeling. A fight breaks out between Batman, the Joker, and his goons with the Joker and the goons beating on Batman pretty well. When Batman gains the upper hand he sees the Joker holding a gun at Rachel's head as he dangles her out of a shot out window. Batman screams to let her go, to which the Joker replies, "bad choice of words," and lets her fall. Batman dives out the window and saves her using his cape to slow their fall as they crash into the roof of a car on the street. The Joker apparently vanishes from the scene.

The next day, Wayne tries to figure out what the Joker is after. Alfred relates a story of when he was in Burma with friends attempting to nullify the local criminals by bribing them with jewels. One thief however, tossed these bribes away and continued to raid the local convoys. When Bruce seems confused over this behavior Alfred informs him that some men can't be reasoned with, they don't want anything in particular, that they kill for sport. Alfred observes that they just want to watch the world burn, as Bruce fixates on the Joker's face on a monitor.

Batman is seen on the edge of a rooftop listening in to cell phone frequencies when he overhears a plot against Harvey Dent. Gordon rushes to the apartment with Ramirez and Batman to find two policemen murdered, with the last names "Harvey" and "Dent." Ramirez begins to blame Batman, but Gordon cuts her off. As Batman removes a piece of concrete wall that contains a bullet used in the murders in hopes of finding evidence, Gordon notes that the Joker has left an advance copy of tomorrow's newspaper indicating the death of the mayor.

At Wayne Enterprises, Fox meets with Wayne's accountant Reese, who claims to know about certain problems with Wayne's funding in research and development, claiming that Wayne has some sort of government project with cell phones for the army underway. He also uncovers Fox's designs for the Batmobile/tumbler. He tells Fox the he wants $10 million per year for the rest of his life to keep this a secret. Fox smiles and says, "Let me get this straight. You think that your client, one of the wealthiest and most powerful men in the world is a secretly a vigilante who spends his nights beating criminals to a pulp with his bare hands, and your plan is to blackmail this person? Good luck."

Fox helps Wayne reconstruct the bullet taken from the murder scene and produces a fingerprint. Fox asks him if he has reassigned the R&D department. Bruce acknowledges that he has, claiming he is playing this one "close to the chest."

Wayne traces the bullet fingerprint's owner to an apartment overlooking the funeral speeches for Commissioner Loeb and takes off on motorcycle as Bruce Wayne.

As the ceremony continues on the street below, Wayne inspects a room where he believes the Joker might be, and he finds several men tied up. They tell Waye that their uniforms were stolen. Wayne inspects binoculars pointed out of a blinded window. The window blind is connected to a timer. As the timer reaches zero, the blinds quickly raise, and the police snipers positioned around the area all shoot in that direction, at Bruce Wayne. At the same time, the Joker, who had removed his makeup and played himself off as a member of the honor guard for the ceremony, turns and takes a shot at the mayor, but Lt. Gordon dives in the way, getting shot in the back and falling. Everyone panics and runs, but the police grab one member of the honor guard and haul him into a truck. Dent himself climbs in the truck, and upon inspecting the criminal, sees that the name-tag on his uniform reads 'Rachel Dawes'. He calls Rachel and informs her that she's been targeted, and to get to the safest place she can, which in her case is Wayne Manor. he tells her he loves her, but there is no answer from Rachel.

Gordon's family is visited at home, to inform them of the death of Gordon at the funeral ceremony.

Meanwhile, Batman enters a club and grabs Maroni after beating on his men. He interrogates Maroni, who claims that he should have brought him to a higher window to intimidate him. Batman drops him out of a window, injuring his legs and learns that Maroni has no idea where the Joker is. Maroni explains that the Joker has no friends and no one will give him up because unlike Batman, he plays by no rules.

As Dent is interrogating the captured so-called honor guard member about what he knows about the Joker, he is enraged and holds a gun to his head. He flips a coin for his life. As he flips a coin again to get a more desirable result, Batman shows up and snatches the coin in midair. He informs Harvey that this criminal is a paranoid schizophrenic, and that he won't learn anything from him. He also tells Harvey that if anyone saw this unjust way of interrogating someone, all that good work that Dent's done for Gotham would be lost. He tells Harvey to hold a press conference the following day, because he wants to use that opportunity to turn himself in. As Batman leaves, Harvey yells at him that he can't give in.

Bruce arrives back in his penthouse to find Rachel waiting. She tells him that turning himself in will not stop the Joker's murderous rampage, but Bruce says he has enough blood on his hands already. He reminds her that she promised him that they would be together if and when he hung up the mantle of Batman. She tells Bruce not to make her his only hope for a normal life and they share a kiss. She tells Bruce that if he turns himself in as Batman that the city will never let them be together.

Back at Wayne's secret base of operations for Batman, he and Alfred begin destroying everything that might tie Lucius Fox or Rachel to Batman. Alfred tries to talk Bruce out of it, asking him to endure these trying times and allow Batman to make the right choice that nobody else can for the good of the city. Bruce explains that Batman cannot endure the responsibility for innocents dying, especially where Rachel is concerned.

The next day, at the press conference, Harvey attmepts to reason with the assembled press and police to not give in to the fear that the Joker has unleashed upon the city. He agress that Batman is a vigilante but that the people of Gotham should hold him accountable, and not give in to the whims of this terrorist known as the Joker. However, the people are overcome with fear, crying out "No more dead cops," to applause indicating that Harvey will not be able to sway them. Upon his failure, Harvey announces that HE is the Batman, and gets handcuffed and taken away. Bruce Wayne is shown with a look of confusion on his face.

Rachel, watching the news conference at Bruce Wayne's penthouse, confronts Alfred over Bruce's seeming cowardice in allowing Harvey to take the fall when he claims to be The Batman. Alfred explains to Rachel that Batman is instead allowing himself to be something else besides a hero, mainly a figure outside of the system that the people can both turn to or blame in times of need, that Batman can 'take it". Rachel gives Alfred a letter for Bruce and tells him to give it to Bruce when the time is right. When Alfred asks what it is, she tells him it is open then hugs him and departs to see Harvey as he is being transported to the County lock-up.

While being taken to a convoy that will transport him to a county, Harvey explains to Rachel that this is Batman's chance. He then pulls out a coin and says "Heads: I go through with this," and flips it, landing on heads. When Rachel tells him that he can't leave something like that to chance, he tosses her the coin, revealing that it is a two-headed coin. During this transport, he's planning on getting attacked by the Joker, and he's planning on Batman to come and save him, and to capture the Joker. The convoy takes off.

While transporting Harvey, the Joker and some goons start taking out the police cars in a large semi truck. He pulls out an RPG and beings firing at the armored truck carrying Dent. Batman drives through in his 'tumbler/batmobile' and attempts to stop the Joker, and gets hit with the RPG in the process. His car takes 'catastrophic' damage, and he's forced to eject. However, the ejection in this car is a bike, that deploys out the front of the car. This bike becomes known as the 'Batpod'. Batman chases down the Joker on his Batpod, and after firing some cables at the truck and weaving them through some light poles and buildings, flips the truck completely over. The Joker emerges with a tommy gun and shoots at Batman, who is speeding towards him on his Batpod, all the while screaming 'I want you to do it! Come on! HIT ME!'. Batman honors his own non-lethal code and swerves around the Joker then crashes into the flipped truck, falling to the ground. As the Joker jumps on him with a knife, a police officer holds a gun to the back of his head, and upon removing his helmet and mask, shows that it was Lt. Gordon, who wasn't really dead after all. The Joker is hauled away to jail. Harvey gets out of the truck and into a cruiser, and says he is off to see his girlfriend.

At Gordon's Major Crimes Unit building, Gordon is promoted to Commissioner by the Mayor. The Joker shares a cell with a large man who complains about his insides hurting. Commissioner Gordon, after reuniting with his family, gets a call explaining that Harvey never made it home. He returns to the prison to interrogate the Joker. During the interrogation, Batman appears and starts beating on the Joker, trying to find out where Harvey is. The Joker gets under Batman's skin telling him that they are both freaks and that when the people of Gotham no longer view Batman as a necessity, they will turn on him. Batman becomes enraged and puts a chair under the door and beats the Joker savagely, but The Joker just laughs and defiantly tells Batman that there is nothing he can do to him to hurt him and that he actually enjoys the beatings. The Joker sadistically reveals that not just Harvey, but Rachel are in separate locations, both tied up and strapped to explosives and oil cans that will explode in a short amount of time. He gives the locations of the two, saying that he only has time to save one of them and that he must make a choice that will violate Batman's "code" of non-lethal means...that one of them will die since batman cannot save them both. Batman heads off, telling Gordon that he's going after Rachel. Gordon gets some men ready and heads off after Harvey.

As Batman and the police are rushing towards the two prisoners, Harvey awakens to hear Rachel's voice. Whoever captured them set up an intercom system so that the two can communicate. Harvey tells Rachel that everything will be OK, and Rachel tells Harvey that she wants to marry him. While Dent's trying to hop around in his chair trying to find something sharp to cut his ropes with, he falls over and knocks an oil drum down, and the oil spills all over half of his face. Meanwhile, back at the jail, the Joker tricks a cop and holds him hostage, and he tells the other cops he just wants his phone call. Upon getting a cell phone and dialing a number, the large man that was in the cell with him blows up. The Joker had cut him open and implanted a cell phone triggering device inside of him. The Joker grabs Lau and flees the jail.

Batman arrives at the address that the Joker had told him Rachel was at, but when he opens the door, he finds Harvey Dent who screams, "NO!!! Why did you come after ME??" Gordon arrives at the supposed location for Dent but the warehouse explodes and Rachel is killed. As batman saves Dent by carrying him out of the warehouse the explosion ignites the oil that saturated Dent's face, and he gets lit on fire and taken to Gotham General Hospital. Comissioner Gordon visits Dent in the hospital, and leaves him the two-headed coin that they found at Rachel's site of death. One side of the coin is still shiny, while the other side is scraped and burnt, alluding to Harvey's eventual transformation to Two-Face.

Alfred reads Rachels' letter. She explains that she is going to marry Harvey Dent and that when she told him that she would be with him when he no longer need to be Batman that she meant it. However, she realizes that he will always be Batman so she will always be there as his friend.

Bruce expresses to Alfred his devastation behind losing Rachel and that he feels responsible for inspiring madness and death. he tells Alfred that she was going to wait for him so Alfred chooses not to give him her letter, saying the time is not right.

Alfred informs him that with Harvey Dent hospitalized, it will be up to him alone to fight the crime in Gotham City. Meanwhile, Harvey wakes up in the hospital with a large bandage over half of his face, finds his now scarred two-headed coin, and screams out in his frustration behind losing the one person he loved.

Commissioner Gordon visits Dent and tries to tell him how sorry he is for what has transpired, questioning why Dent refused skin grafts and how he can stand to be in unrelenting agony over his disfigurement. Harvey is filled with rage for Gordon not listening to him when he warned Gordon not to trust the corrupt officers that Dent investigated during his time in Internal Affairs which has resulted in Dent's disfigurement and ultimately Rachel's death. Dent asks Gordon to tell him the nickname they had for him when he was in internal affairs to which Gordon replies "Harvey Two-Face." As Gordon leaves an emotionally devastated Harvey, he runs into Maroni in the hallway who tells him that the Joker has gone too far and that if Gordon wants the clown, he knows where he will be.

Wayne's accountant Reese appears on a news show claining to be able to tell the world who Batman is. He tells Gotham that he is going to reveal Batman's identity, but before he can, the Joker calls in to the show saying that he doesn't want this lawyer to ruin his fun. He says that if the lawyer is not killed within 60 minutes, he is going to blow up a hospital. This triggers the police to rush in and protect the lawyer, and try to carry him to safety. At the same time, other police are evacuating all of the hospitals in Gotham City. When they get to Gotham General, a police officer attempts to evacuate a nurse in Harvey Dent's room, which then turns out to be the Joker, and he kills the cop. He then gives a great monologue to Harvey (now Two-Face) Dent, about how he needs to introduce a little anarchy, and how easy it is to bring down all the good people in the world. Joker unties Dent and gives him a gun. Dent, bent on revenge and now believing everything in the world should be decided by chance, flips the double-headed coin to decide whether or not to shoot Joker which Joker agrees is only fair. Though we don't see it, the coin obviously lands on the clean side since the next scene shows Joker leaving Gotham General Hospital as it blows up in the background.

Afterwards, the Joker appears on TV again, forcing a TV icon to read out his plans. He reads that Gotham City now belongs to the Joker, starting that very evening. Anyone that doesn't want to be a part of his game should leave now, but they are going to have a hard time leaving the city by the bridges. He alludes to the fact that something big was going to happen that very night. During which, Two-Face enters a local bar where the 'dirty' cop that had picked him up from the armored car scene hangs out. After questioning him, he flips a coin which lands on the dirty side of the coin, and he kills the cop. At the same time, Batman uses Fox's 'cell phone sonar' technology to somehow turn every single cell phone in Gotham into a sonar device, giving him the opportunity to spy on everyone in Gotham. He calls Fox in, and tells him to monitor the screens, and give him updates on the Joker's location when he sees him.

Dent continues to question mob members, trying to uncover the identity of the dirty cop that kidnapped Rachel. When confronting Maroni in Maroni's car, he learns that the other cop is Ramirez, a close friend of Commissioner Gordon's. He then flips the coin for Maroni, which lands on the clean side. "Lucky Man," he remarks before he flips it again. It lands on the dirty side and he buckles up. "But he's not so lucky." Dent then shoots Maroni's driver and the car veers off the road and flips into a streetlight. Meanwhile, Two large ferries leave Gotham due to the Joker's threats. One is inhabited by criminals that were imprisoned, the other is packed with innocent citizens - the city's bridges apparently being wired with explosives. While sailing off, the two boats completely lose all power and their engines die. Both ships eventually realize that there are explosives strewn all about the boat, and they both find detonators. It is at this time that the Joker's voice is heard over the loudspeaker of both ferries, and he informs them that they are part of a social experiment. The detonator on each boat is for the other boat. One ferry must press the button and destroy the other boat by midnight, or else the Joker will destroy both boats. This brings about much chaos in both boats, and a lot of soul searching about morality and about if anyone could actually do such a thing. One of the largest and meanest-looking convicts makes a speech about the officer holding the trigger not knowing how to take life, then goes up to the officer and asks to take the trigger so he himself can do what the officer should have done ten minutes ago. The officer hands the convict the trigger and the convict promptly throws it out of the ferry, making it impossible for anyone on the convict ferry to blow up the 'innocent' ferry.

Fox finds the Joker, who is in a tall building with many clown guards. Batman notifies Gordon of the location, and speeds off towards the building. Meanwhile, Two-Face forces Ramirez to call Gordon's family and tell his wife and two sons to meet him at the exact spot where Rachel was killed. They believe her because they trust her. Afterwards, Two-Face flips a coin for Ramirez's life and it lands on the clean side, so he just knocks her out and heads on. As Gordon arrives at the building where the Joker is, he gets a call from his family telling him they are being held captive by Two-Face in the place where Rachel was killed. Gordon rushes off to save his family as Batman breaks in to the building. After realizing that the clown guards were actually hostages and some scientists were the enemies, he beats down some SWAT members in order to prevent them from killing the clown guards, and he disables the scientists as he makes his way up to the Joker's location.

When he finally confronts the Joker, the Joker sends three ferocious dogs after him, and while Batman fights them off, the Joker beats him brutally with a blunt metal object, and eventually throws him close to the edge of the building, trapping him under a metal beam. At the same time, the two boats are still debating what to do with the detonators. No one wants to get their hands dirty, so no one will push the button. The Joker, on top of Batman while holding him down, gets depressed when neither of the ships blow up by midnight. As he's about to destroy the two boats, Batman fires his gauntlet darts at him and throws him over the edge of the building. Before he can hit the ground, however, Batman fires one of his grappling gun tools at him and saves him. While hanging in front of Batman, the Joker tells him that the two of them are destined to fight forever, and how batman really IS incorruptible. The Joker reveals to him, however, that his real plan was to engineer the fall of Gotham's White Knight, Harvey Dent, since that would introduce much more chaos when a good man like Dent is shown descending into chaos and evil. Batman heads off to find Harvey, while the SWAT team captures the Joker.

In the building where Rachel died, Gordon arrives to see Two-Face holding his family hostage. Two-Face knocks him to the ground tells him that he's going to make him suffer just as he did, as he grabs his young son Jimmy and prepares to flip the coin for his fate. Batman arrives and tells him to stop, and to blame the people responsible for Rachel's death. So then Two-Face flips the coin for Batman, which lands on the dirty, scarred side, and Two-Face shoots him. He then flips the coin for himself and it lands on the clean side. As he's flipping the coin for Gordon's son he tells Gordon to lie to the boy and tell him that everything will be alright, just as Dent himself had to tell Rachel earlier seconds before she was killed. Batman gets up and tackles him and they fall off of the building together. Unseen by them, the coin lands on the clean side. Batman hands Jimmy up to Gordon as Batman himself falls to the ground next to Two-Face, who lies motionless.

As Gordon climbs down to check on Batman, he laments that the Joker actually won by turning the best of them, Harvey Dent, and tore him down, Batman tells Gordon that the people of Gotham must never know about Harvey's killings, and to blame them on Batman himself, basically turning himself into an outlaw in the eyes of the people of Gotham. This way, the Joker cannot win.

We see a montage of Commissioner Gordon and other members of the Gotham City Police Department gathered at a memorial to Harvey Dent (not clear whether he is dead or not) and later smash the batsignal above the MCU building. Alfred burns Rachel's letter as batman explains that the people do not need the truth right now. Fox enters his name into the wall of surveilance computer and is pleased when it destroys itself, restoring his faith in The Batman as a force of good.

As the cops begin to chase Batman, he hops on his Batpod and speeds out into the night. Gordon notes to his son that Batman is the hero Gotham derserves, but not the hero it needs right now. That was Harvey Dent.

So they will hunt him because he can take it. Because he's not a hero...he's a silent guardian....a watchful protector...A DARK KNIGHT...

Approaching its 200th anniversary, Gotham City's leaders fear that the high level of criminal activity will deter citizens from attending the celebrations. Gotham's mayor William Borg orders District Attorney Harvey Dent to make the city safe again, in hopes of revitalizing local business. Dent, in turn, targets mob boss Carl Grissom, who sponsors much of the criminal activity within Gotham and has paid off a significant segment of the police force.

Meanwhile, a dark vigilante dressed as a bat has attracted the attention of both the police and the local media. Newspaper reporter Alexander Knox is attempting to investigate, but his questions are deflected by skeptical cops, including Lt. Eckhardt, one of many police officers on the take from Grissom. After stonewalling Knox, Eckhardt is shown taking a payoff from Grissom's second in command, Jack Napier.

Grissom, on discovering that his mistress is involved with Napier, sets him up to be killed by Eckhardt in a raid on Axis Chemicals. The plot is foiled by the arrival of Police Commissioner James Gordon, who wants Napier taken alive, and Batman. Batman captures Napier, but releases him when Bob the Goon holds Gordon hostage at gunpoint. Batman vanishes, and in the confusion, Napier shoots and kills Eckhardt, then attempts to shoot a re-emerged Batman. The latter deflects his shot, sending shrapnel into the former's face. Napier falls over a railing into a vat of chemicals, presumably to his death. Although surrounded by the police, Batman escapes the scene.

Batman, as we discover, is actually billionaire industrialist Bruce Wayne, an orphan who lives alone in the large mansion Wayne Manor, with only his butler Alfred Pennyworth in attendance. At a fundraising party, Bruce meets and falls for famous photojournalist Vicki Vale, recently arrived in town to cover the "Bat Man phenomenon."

Napier, in the meantime, is not dead but horribly disfigured, with white skin, green hair, and a permanent grin (after a botched reconstructive surgery attempt). Already erratic, the trauma has apparently driven him completely insane. Calling himself "The Joker", he kills Grissom and usurps his criminal empire. His first scheme is to spread terror in the city by creating hygiene products that can kill by fatal hilarity when used in certain combinations, laced with a deadly chemical known as "Smylex." Following the death of a news anchor on-air, the city becomes paralyzed with fear. Making war on several fronts, the Joker then sets a trap at the Gotham Museum of Art for Vicki, with whom he has become smitten; his fellows start to slash and deface the entire legacy of Western Art, but as one of them approaches to Francis Bacon's Figure with Meat, the Joker stops him saying "I kinda like this one". Batman intervenes and saves Vicki, to whom he then gives the secret of the Joker's chemical combinations. Batman renders her unconscious, and she awakes at home. Incensed at Batman eluding him while taking Vale and ruining his poisoning scheme, the Joker vows to eliminate the mysterious vigilante for interfering with his plans.

Vicki's apartment is then the scene of a confrontation between the Joker, who has come to woo her, and Bruce, who has come to try and confess about his double-life but not getting very far. After Bruce challenges the Joker to a fight, the Joker pulls a gun and asks him: "Tell me something, friend. Have you ever danced with the devil by the pale moonlight?" He then shoots Bruce. The Joker then leaves amid his own hoopla, and Vicki is shocked to see that Bruce has disappeared, leaving behind only a metal platter which he used as an impromptu bulletproof vest.

That confrontation confirmed for Bruce that the Joker is actually the man who murdered his parents many, many years ago in Gotham. The final clue was that his parents' murderer said the same phrase to him as The Joker said in Vicki's apartment ("Ever dance with the Devil by the pale moonlight?"). As Bruce grapples with this memory, he is shocked by the sudden appearance of Vicki in the Bat Cave; Alfred having decided that she deserved to know the truth.

The Joker has put his own plans in motion to upstage the city's canceled anniversary celebrations with a grand spectacle: a nighttime parade at which he will dispense $20 million in free cash. Vicki and Knox are there to cover the pandemonium, and they notice strange tanks on the balloons. In the middle of his generosity, the Joker begins gassing the crowd. Batman arrives in his bat-shaped jet(in this film called the batwing) and snatches the balloons away to carry them out of the city. Furious, the Joker shoots Bob the Goon, his number one thug. Batman returns to make a strafing run on the Joker, who responds by shooting down the jet with an insanely long-barreled revolver. Vicki approaches the downed craft but is captured by the Joker, who leads her to the top of Gotham Cathedral. Dazed but not finished, Batman pursues. At the top of the cathedral, the two adversaries confront each other in single combat.

In a moment of opportunity, the Joker pulls Batman and Vicki off the belfry, where they cling to the ledge for their lives. as The Joker begins mocking them his helicopter appears and he grabs hold of a dangling ladder, about to escape. Batman shoots a wire around the Joker's leg, connecting it to a stone gargoyle on the ledge. As the Joker is lifted away, the wire pulls the gargoyle loose and he plummets to his death.

The movie ends with Commissioner Gordon announcing the Gotham police have arrested all the Joker's gang remnants who were not killed by Batman, and unveiling the Bat-Signal supplied by Batman with a note promising to return if the city needs him.

Part I of the series begins with a karate tournament at Angel Grove's Youth Center. Competition in sparring has been eliminated down to two final contestants: Jason Lee Scott, the Red Ranger, and newcomer Tommy Oliver. Tommy quickly takes a 4-2 lead, but Jason battles back to end the match in a 4-4 draw. Jason is impressed with Tommy, as are Zack Taylor, the Black Ranger, and Billy Cranston, the Blue Ranger. Kimberly Hart, the Pink Ranger, also shows some interest in Tommy, a fact her best friend, Yellow Ranger Trini Kwan, is quick to pick up on.

The next day at school, Tommy stands up to Bulk and Skull, the school bullies, when they harass Kimberly. She is further impressed and invites him to a study date at Ernie's Juice Bar.

But Rita Repulsa, also impressed with Tommy's abilities, sends a squad of Putties to attack him while he is on his way to meet Kimberly. When he defeats them, she captures him and takes him back to her palace on the moon. There she coats his body with magical wax and casts a spell on him, brainwashing him into becoming her servant. He swears allegiance to his "empress", and she assigns him to destroy Zordon, the Command Center, and the Power Rangers. To fulfill the mission, she gives him the Dragon Power Coin, and he morphs into the Green Ranger.

The Evil Green Ranger goes first to the Command Center, which he can enter since he possesses the Dragon Power Coin. He finds Alpha 5 recharging, and inserts a CD-ROM containing a computer virus, causing the droid to convulse and stumble all over the Command Center. Zordon, who was in a meditative state when Tommy entered, demands that the intruder reveal himself. Tommy does, boasting of his newly acquired power. Then, despite Zordon's offer to help him break the spell, he breaks the dimension contact with Zordon, tearing the Command Center's computers to pieces and ripping up the circuitry.

In spite of the virus, Alpha manages to make contact with the other Rangers, who were cleaning Billy's car, the RADBUG. His erratic talking and the failure of the communicators and the teleporter mechanisms alerts the Rangers to the fact that there is something seriously wrong. They take the RADBUG to the Command Center, where they are shocked to find the place totalled, Alpha staggering around talking gibberish, and Zordon gone. Billy removes the CD-ROM from Alpha's system, rendering him semi-operational, and try to figure out what happened. But Alpha can tell them nothing, since the virus scrambled his memory banks.

Meanwhile, Rita uses her magic wand to grow Goldar to gigantic size. After a brief battle with some Putties, the Rangers summon their Dinozords, combine them into the Megazord, and draw the Power Sword to fight Goldar. Suddenly, Goldar disappears, and the Green Ranger breaks into Megazord's control center, kicking the other Rangers out to the ground below. He then single-handedly defeats all five Rangers in combat.

They return to the Command Center, stunned at the beating they took from this "guy in a green costume." Suddenly, Alpha lurches, falls forward, and shuts down; the virus is still in his system. Jason grimly warns the others that they have only been through round one of what will be a major battle. They end the episode watching the Viewing Globe as Green Ranger vows their downfall.

Part II begins in the Command Center, as the Rangers debate their options on how to deal with the Green Ranger. Billy and Trini finish repairing Alpha, eradicating the virus from his circuits. While the Blue and Yellow Rangers set to work repairing the computers, the others return to town.

Tommy returns to the earth with orders from Rita to stay put until she calls for him again. After she leaves, he encounters Bulk and Skull, who want revenge for the way he humiliated them earlier. They demand an apology from him. Tommy's eyes, glowing an evil green, shoot sparks at Bulk and Skull's feet, scaring them silly and causing them to jump into a dumpster for cover. After Tommy leaves, they both agree that Tommy needs his eyes checked, wondering what is going on with him.

Jason, his pride hurt from his encounter with the Green Ranger, is taking out his frustration on a punching bag at the Youth Center. Slowly it dawns on both him and Zack that it must have been the Green Ranger who wrecked the Command Center. Meanwhile, Kimberly, who goes to ask Tommy why he never showed for the study date, notices a change in Tommy's personality. He rudely tells her he doesn't need her to worry about him and that she is not the center of his universe. Kimberly is offended and brokenhearted, and she expresses her feelings to Zack. Zack tells her to forget about Tommy for the time being, since they have "bigger problems to worry about".

Back on the moon, at Goldar's suggestion Rita decides to put Tommy through one final test: if he can defeat another band of Putties using only his natural karate skills, he will be given the Sword of Darkness, a legendary weapon which Rita's forces used against Zordon's Rangers millennia ago. Rita wants to give him this weapon because, as Finster explains, it will allow Rita to maintain control of Tommy forever, provided the Sword is not destroyed. The only one who knows of its power is Zordon, and he is not around to tell the other Rangers to destroy it. Rita and her minions go down to earth together to watch Tommy battle the Putties. Tommy soundly defeats them, exceeding Rita and Goldar's expectations, and is rewarded with the Sword.

Later, Jason meets Tommy and tells him that a workout session between the two of them will have to wait due to an "emergency". Tommy says he understands, and Jason turns to leave. Then Tommy zaps Jason with his Power Coin and sends him to Rita's Dark Dimension. There the Red Ranger encounters Goldar, who has stolen his morpher. Jason finds himself in a desperate struggle to regain his morpher and stay alive.

Zack and Kimberly decide to go back to the Command Center in the RADBUG and rejoin Billy and Trini, who have by now repaired the computers and restored them to partial power. Attempts to regain contact with Zordon fail. The Rangers become highly concerned about Jason's disappearance. Jason continues his struggle to get his morpher back from Goldar, who beats him around with sadistic pleasure.

The Green Ranger reappears and taunts the Rangers. In Jason's absence, Zack decides that they will go into battle to try to learn his indentity. But with Jason gone and the Green Ranger armed with the Sword of Darkness, he dispatches them even more easily than before. However, they call on the Megazord and force him to retreat. Rita is highly annoyed by this setback until Squatt and Baboo remind her that Jason is still their prisoner. The episode ends with Jason at the mercy of Goldar, who has received orders from Rita to finish him.

While the Power Rangers attempt to find Jason and renew contact with Zordon, Jason continues his desperate confrontation with Goldar, trying to hide in the Dark Dimension's mist. Kimberly continues her search for Jason at Ernie's Juice Bar. When Bulk and Skull offer to help, demanding a kiss as payment, quick-thinking Kimberly tricks Skull into kissing Bulk! Leaving the dimwitted duo to argue with each other, Kimberly resumes her search and encounters Tommy. She tries to ask Tommy about Jason, but he replies that Jason didn't show up for a practice session they had scheduled, taunts her for being a worry-wart, and walks off. She and Zack go to ask Tommy about Jason again; but Rita, realizing that they might suspect him of being the Green Ranger, sends a squad of Putties to attack. This gives Tommy time to slip away. Zack and Kimberly wonder why the Putties didn't attack him, but suspect nothing.

The Green Ranger, his secret out of danger, gains Rita's permission to take Goldar's place in the Dark Dimension and kill Jason. Goldar leaves, jealous of being deprived of the honor. Words are exchanged between the Red and Green Rangers. The fight begins anew. Jason grabs his morpher, but before he can use it, the Green Ranger pins him to the ground and takes a moment to gloat over his victory. But just before he can strike the final blow with the Sword of Darkness, Billy, who has repaired the communicators and teleportation devices, finally isolates Jason's whereabouts and teleports him back to the Command Center.

Goldar, furious, harshly reprimands the Green Ranger, who begs for another chance. Goldar replies that he'll have to check with Rita and leaves the Green Ranger in the Dark Dimension for the time being. The Green Ranger undergoes further practice with his karate skills in preparation for another battle with the Power Rangers. When he does ask Rita for another chance, Rita tells him to be patient because the time is not right.

The reunited Rangers discuss Jason's experience, compare notes, and realize that Tommy isn't being honest with them, but they still don't draw any connection between Tommy and the Green Ranger. And they are no closer to finding Zordon.

Meanwhile, Scorpina, one of Rita's most dangerous minions, rejoins Rita after 10,000 years, and she is sent to attack Angel Grove. The Rangers do battle with her, further taxing themselves until she is recalled. While the Rangers recover in the Command Center, Alpha 5 finally finds a way to track down Zordon. He is beginning to renew contact when Rita sends a giganticized Goldar to attack the city, intending to force the Rangers to summon the Megazord, all the while cooking up a spell to cause a solar eclipse and drain the Megazord, energized by solar power, of it's energy. The Rangers end the episode watching desperately on the Viewing Globe as Goldar destroys several buildings in downtown Angel Grove.

Realizing that they have no choice but to fight yet again, the Rangers draw their morphers. However, when they try to morph, sparks fly and the Command Center blacks out. Apparently, focusing the energy on finding Zordon drained power from the Morphing Grid, and nothing (morphers, Zords, communicators, and most of the lights in the Command Center) works. Goldar manages to tear a section of Angel Grove apart before Billy reconfigures the Command Center and restores power. The Rangers morph and go to fight Goldar.

After a short exchange with Scorpina, some Putties, and the giant Goldar, the Rangers have a brief confrontation with Rita. She sends Goldar to the beach, carrying a bus with Bulk and Skull, who were trying to flee the city, in one hand. The Rangers teleport after him, trying to save the troublesome duo. After a few tense moments of watching Putties pushing the bus toward a cliff, the Rangers call on their Zords, and the Megazord catches the bus just before it falls, depositing an overjoyed Bulk and Skull back on the cliff.

Meanwhile, Rita again sends Tommy, who has been practicing swordplay in the Dark Dimension, to the Command Center, this time to get rid of Zordon for good. He pulls the plug on Alpha, exchanges words with a partially restored Zordon, and then presses a few buttons to undo all of Alpha's work in bringing him back. He is just about to leave when, much to his surprise, Alpha reactivates. Having accessed his "backup power generators", the quick-thinking robot traps him in a force field. Unfortunately, all the progress made in finding Zordon is lost, to the dismay of Alpha and the glee of the Green Ranger. Alpha indignantly sets into motion a program to learn Green Ranger's indentity.

The Megazord, which is dealing a heavy beating to Goldar, suddenly finds itself fighting Scorpina as well, who has also been enlarged and now sports a hideous appearance. Furthermore, Rita's solar eclipse begins and drains the Megazord of its power, so that it is overwhelmed by the dual attack and knocked to the ground. Jason calls for the Power Sword to give the Megazord a power boost. It works, and the Megazord is immediately back on its feet when it grabs the sword, going on the offensive again. Rita, determined not to lose the fight, uses a spell to free Green Ranger from the Command Center force field (to Alpha's consternation), grows him to giant size, and sends him into battle as well. The Megazord is surrounded by Goldar, Scorpina, and the Green Ranger, and doesn't have enough power to finish the battle. Scorpina further weakens Megazord by electrocuting it with her stinging tail, while Goldar and the Green Ranger combine their swords to deal Megazord a crippling shockwave The Rangers are thrown out from the exploding Megazord, demorph involuntarily, and watch helplessly in shock as the defeated Zords fall into a crevice in the earth and are consumed by lava.

Back in the Command Center, all the Rangers except Jason are considering surrender, with Jason and Alpha 5 desperately trying to persuade them otherwise. But with the Zords totalled and the chances of finding Zordon under ten percent, there isn't much hope. However, Alpha does have some good news; while Green Ranger was trapped in the force field, the computer learned his identity. The episode ends with the Rangers looking into the Viewing Globe and reacting in utter disbelief upon discovering that their nemesis is, in fact, Tommy.

Upon discovering that Tommy is the Green Ranger, the Power Rangers are at first in shock and denial. But once they face the facts, they split up to find him, on a quest to save him from Rita's power.

Kimberly goes to the Youth Center and finds Ernie, Bulk and Skull watching the news reports of the last battle. Bulk and Skull are making ridiculous claims about being the ones who scared Goldar away; to this Kimberly responds, "Dream on!" Then she asks Ernie if Tommy is around, and he directs her to the weight machines where Tommy is working out. She tells him that she knows his Green Ranger identity. She is left speechless when he glares at her with eyes glowing green, addresses her as the Pink Ranger, and threatens to destroy her and the other Rangers and bring the world under Rita's rule.

Meanwhile, toasting her victory over the Megazord in her palace on the moon, Rita decides to complete the destruction of the Power Rangers by reviving the Dragonzord, dormant for 10,000 years. She gives Tommy the Dragon Dagger, and he assumes control of this new Zord and wreaks havoc on downtown Angel Grove.

The Rangers are discussing Kimberly's encounter with Tommy when Trini frantically bursts in and tells them about this new assault on their city. The Rangers morph into action, but without their Zords, they can do nothing to stop the Dragonzord.

As the Rangers fight a losing battle with Tommy, desperately trying to convince him that he doesn't know what he's doing, Alpha finally succeeds in his search for Zordon. When Zordon returns to the Command Center, he and Alpha revive the damaged Dinozords from their lava prison and return them to the Rangers. Zordon also tells Jason that he must destroy the Sword of Darkness to break Rita's grip on Tommy's mind. Rita, upon seeing the Zords resurrected, gets one of her famous headaches.

A one-on-one duel ensues between Tommy, controlling the Dragonzord, and Jason in the Tyrannosaurus. When the Dragonzord is beaten down, the Rangers call on the Megazord to finish it off. Megazord succeeds and hurls the Dragonzord into the side a mountain.

Once the Dragonzord is disabled, Jason, who has received orders from Zordon to destroy the Sword of Darkness to break the spell, leaps from the Megazord to fight Tommy in person. The Red and Green Rangers battle back and forth in an evenly matched duel. Green Ranger activates his golden chest armor, the Dragon Shield, to ward off Jason's attacks. Just when it appears Green Ranger will win, Jason finally throws his Power Sword at Tommy, knocking the Dragon Dagger and Sword of Darkness out of his hands. Green Ranger, unprepared for this blow, is thrown on his back. Jason draws his blade blaster, says, "It's all over, Tommy!", and shoots and destroys the Sword of Darkness. Rita's spell is broken, and Tommy involuntarily demorphs.

When Tommy revives, he is remorseful over what he has done. But Jason and the other Rangers are quick to forgive him, taking into account that he was under an evil spell, and Jason invites him to join the team as the sixth and final Ranger. Tommy is reluctant at first, but the others convince him that he belongs with them and can use his powers against Rita. At that, Tommy agrees to join the team.

From the Command Center, Zordon and Alpha watch what Zordon calls the fulfillment of a historic prophecy, that the Sixth Ranger would fight for justice rather than evil. Rita and her minions, meanwhile, are enraged that they lost the battle when everything was going so well for them, and Goldar promises vengeance.

Meanwhile, Zordon summons the six Rangers back to the Command Center. He praises Alpha for displaying leadership in his absence, and commends the five main Rangers for their refusal to give up when the odds were against them. He then confirms Tommy as the Green Ranger, and Tommy promises to obey the Rangers' three main rules. He also tells them that Dragonzord can go into Battle-Mode by combining with the Mastodon, Triceratops, and Saber-Toothed Tiger Dinozords. Finally, Billy presents Tommy with his own wrist-communicator, Jason and Tommy shake hands in friendship, and the six Rangers huddle up for a Power Ranger high-five.

Ashley strolls through the halls of Angel Grove High and spots Bobby come down the stairs. He's talking to some girl, and then another girl walks up and starts talking to him. He excuses himself from the barrage of bimbos and makes his way to Ashley's locker. She pretends she wasn't watching him, but thankfully he's too dumb to have noticed. He brings up the dance that'll be occurring on Saturday, Ash needs to be hosed off from the heat of anticipation as she waits for him to ask her, but all he does is ask for dance lessons he thinks he needs. She agrees to do it tomorrow, when Cassie shows up and takes Bobby off to the park as they planned. Cassie walks off in arm with the reanimated beef patty they call Bobby, turning around and waving to Ashley with a mocking finger wave. Ashley's left furious, until she notices salvation waiting just behind her. TJ is at his locker (which means, by the by, all five Ranger teens have lockers located next to one another), acting like a normal human being instead of a dog in heat like everyone else in this episode so far. Ashley asks Teej to go play catch with her at the park, something he thought she didn't like. She says that maybe she changed her mind, slams his locker door shut and pulls him off to the park in flash. Soon at the Angel Grove Park, we find Cassie sitting on a bench playing her string guitar, with Bobby sitting against a tree nearby. He seems entranced by the "purty music". Ashley and TJ are playing catch at the park. Suddenly, Ashley hears music. She walks over and finds out that Cassie is playing her acoustic guitar and singing for Bobby. Cassie plays her acoustic guitar and sings for Bobby. Her voice is so sweet and beautiful and her guitar playing is very gentle and beautiful. Bobby loves Cassie's music, so does Ashley. Ashley smiles. Tears begin to stream down Ashley's beautiful blue eyes. Cassie finishes her song and Ashley and Bobby clap. Ashley says "That was a great song, Cassie!" Cassie smiles and says "Thanks, Ashley!" Bobby says "That was a beautiful song, Cassie!" Cassie smiles at Bobby and says tenderly "Thanks, Bobby!" Cassie then says "I love you, Bobby!"
