  • In answering a medical emergency at an archaeological expedition, Kirk confronts the deep hatred of an old love, Janice Lester, who supposedly lies severely ill from celebium radiation. In payment for jilting her back at Starfleet Academy, Dr. Lester arranges for an alien machine to swap her consciousness with that of the captain and takes command of the Enterprise. Once aboard, Kirk (in Lester's body) tries to convince Spock that he is trapped in her body. As a result, Janice (in Kirk's body) conducts a court-marshal with the intent of executing Spock and Kirk (in Janice's body), and later McCoy and Scott, to keep her secret. The crew realize something is seriously wrong with their captain and, not wishing to incur an illegal death-penalty themselves, begin a passive resistance.

  • On the planet Camus II, Kirk meets his old flame, Janice Lester, who is supposedly dying of radiation poisoning. She is a woman scorned and is out to get her revenge on Kirk with whom she was in love many years ago. She has discovered an alien process that will allow her to transfer her essence into Kirk's body and vice versa. Returning to the Enterprise in Kirk's body, she now has command of the Enterprise. Kirk on the other hand is now in Lester's body and can get no one to believe that he is really Kirk. It soon becomes obvious that Lester is incapable of command, leading Spock to accept that she has, in fact, taken over Kirk's body.

  • Captain Kirk's insane ex-lover Dr. Janice Lester forcibly switches bodies with him in order to take command of the Enterprise.
