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

Though her voice is muffled, Dr. Lester protests to Dr. Coleman, "Go to Hell!" a rare case of a "swear" sneaking past the network censors. See more »


After Dr. Lester, in Kirk's body, first arrives on the bridge and starts issuing orders, a wide shot of the bridge and viewing screen clearly shows a blond crewman (stock footage featuring Bill Blackburn) other than Chekov at the navigator station. At the tail end of this shot, Lester/Kirk specifically addresses his order to Chekov. In the very next shot Chekov is suddenly at the navigator station to hear the rest of Lester/Kirk's order.

See Kirk get a sex change and undergo excruciating PMS!
8 December 2006 | by (Bradenton, Florida) – See all my reviews

Kirk and crew land on a lonely planet where one of Kirk's old girlfriends resides (what are the chances of Kirk running into an old lady friend--pretty good it seems for this intergalactic super-stud). The lady appears to be gravely ill, but when she is alone with Kirk, she is surprisingly spry and zaps him--dragging him to an ancient sex-change machine that puts the woman's mind in Kirk's body and vice-versa. The results are unintentionally hilarious--almost as campy and silly as PLAN 9 FROM OUTER SPACE!!! Normally, Shatner isn't exactly subtle in his role as Captain Kirk, and most of us have come to love this campy overacting. However, here, he plays a hysterical and mentally ill woman now residing within his body and the results are just bizarre and completely off the top of the overacting chart! He shrieks and belows and pounds and behaves like a woman who is experiencing every pain of a lifetime of PMS all in one very, very bad day!!!! So, what we have here is a mighty stupid premise combined with shameless overacting as the rest of the actors watch Shatner bellow and wildly gesticulate. No wonder the series was canceled with episodes like this one! Nowhere is there any evidence of the brilliance of earlier episodes.
