After the events of Star Trek II: The Wrath of Khan, the USS Enterprise NCC-1701, under the command of Admiral James T. Kirk, returned Dr. Carol Marcus and Dr. David Marcus--Kirk's son--to Spacelab Regula 1 so that Carol and David would continue their work. The Enterprise then went to Starbase 12 to drop off the surviving crew of the Reliant. The Enterprise then went back to Earth. Admiral Kirk met with Grand Admiral Stephen Turner and requested assignment as the Enterprise's captain. Admiral Turner accepted Kirk's request and granted Kirk command of the Enterprise. Captain Kirk then beamed back to the Enterprise.
