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

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.

Turnabout feelings for 3rd season
15 October 2006 | by (United Kingdom) – See all my reviews

I have recently been watching the repeat of the 3rd season on the British version of the Sci Fi Channel. I remember as a kid back in 1973 being so disappointed with a lot of the third season after the highs of the previous two.

However I have come to enjoy them more now as there were early signs of the series trying to evolve into something for the 1970's (Being cancelled in 1969 it never quite made it). I think if they could have had a little more money to up the production values the third season could have been very good.

Although not one of my favourites - 'The Lights of Zetar' did appear to feature the first computer graphics (see the main view screen shot when the alien is approaching the library planet). Perhaps the special effects guys had been to watch 2001.

So onto the final episode - well it's not bad - if not a little camp - but I agree with the previous comments that Shatner did pull it off well. With a better script it could have rivalled 'What are Little Girls Made of?'

I would love to hear from fellow Trek fans about their favourite 3rd season episodes
