Stardate 3018.2: A woman from Kirk’s past exchanges bodies with him and takes control of the ship.

Dr. Janice Lester, once romantically involved with Jim Kirk, hates the captain because she was unable (and unfit) to become a starship commander as well. She lures Kirk to Camus II, where she has discovered an alien mechanism capable of transferring minds between bodies. Using the device, Lester transfers her consciousness into Kirk's body, trapping his mind in hers. Dr. Arthur Coleman, Lester's partner, makes sure that Kirk is kept sedated, but Spock becomes susupicious and, using a mind meld, discovers what has happened. Lester initiates court-martial proceedings against Spock and all who oppose her, but she is unable to control her temper, arousing further suspicion. When Lester charges McCoy and Scott with mutiny and tries to impose a death sentence, the entire crew realizes that something is seriously wrong. Kirk, with Spock's telepathic assistance, is able to reverse the effects of the mind transfer, and Lester, in her own body once again, falls into a comatose state.
