Star Trek: Turnabout Intruder

Turnabout Intruder was the final episode of season three and of the series. A woman from Kirk's past, driven mad by dreams of power, pretends illness in order to lure Kirk to her side. She then, through the use of alien technology, switches her mind with his, and beams up to the Enterprise, now in control of the ship. McCoy and Spock begin to suspect something amiss due to the captain's erratic behavior, who is doing his best to eliminate the woman within whose body Kirk's mind is trapped. OK, then. This, of course, brings up some interesting and odd questions. If Kirk is trapped in the body of a woman, does that make him a lesbian? And if he/she makes nookie with his body within whom is trapped the woman's personality is that considered mast...er, nevermind. It's complicated. Let's leave it at that.

I never much cared for this episode, but upon rewatching it after so many years I found I liked it much better. Shatner gets the spotlight and does a nice job of playing a hysterical woman. Enhancements are fairly limited, but the ship sailing into a nebula at the end is a nice touch. Nurse Chapel's hair changes from blonde to auburn. One assumes this was not an enhancement. Lt. Uhura is oddly missing from this final episode.
