 The Enterprise finds a 20th century spaceship which contains dozens of people in suspended animation. While investigating, one of the people is revived automatically. His name is Khan, a strikingly handsome Sihk who charms the Enterprise s historian, Lt. McGivers. While recovering, Khan reads up on the nearly 300 years of history he s missed, plus a lot of technical information on the Enterprise. Through research, Kirk discovers that he s a genetic superman that escaped after the Eugenics Wars of Earth s 20th century. But he s too late: Khan and McGivers have gone back to his ship, revived Khan s crew, and returned to commandeer the Enterprise. Before he s successful, the crew manages to lock out some controls of the ship. Khan attempts to coerce the bridge crew to give him the controls by torturing Kirk in a pressure chamber. They don t relent, and Kirk is believed to have died. However, McGivers had a change of heart and rescued Kirk. Together they initiate an gas attack on Khan s crew, disabling them. Once revived, Kirk realized that Khan s people would be a danger to 23rd century society. He then allows them to colonize a planet, which Lt. McGivers chooses to join them on rather than face a court martial.
