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. Written by JW Kearse

The Women's Movement
11 May 2014 | by (United States) – See all my reviews

What a fizzle at the end. Not a terrible episode, but kind of a gratuitous effort to address women's issues, budding in the sixties. This is a chance for Shatner to play a part he never pictured, that of a woman. Actually, he does a very good job. He appears to have studied female mannerisms and adapted them well, and I believe he does it in a respectful way. This could have deteriorated into some silly comedic episode that occasionally diminished the dignity of the series. Of course, it wouldn't have mattered as the death knell had already been delivered. If there is a criticism, it takes a woman who is striking out against the glass ceiling, being portrayed as a you know what in men's clothing. For me, this is quite a forgettable episode. It goes out, not with a bang but a whimper.
