They are a collection of unusual discs, which play the planet's history and (to their surprise) allow their users to travel into the past through the atavachron, a time machine, into the periods each was studying on disc. The crew travels unprepared, McCoy and Spock find themselves locked in a frozen ice age 5,000 years ago, where Spock reverts to the barbaric age of the Vulcans. He becomes very easily agitated, and is intensely attracted to the political prisoner Zarabeth (Mariette Hartley), who enjoys getting company but tells them return is impossible.

Trivia

The sound effect used for the Atavachron is the experimental time code broadcast by radio stations WWV and WWVH in the 1960s. A time code seems appropriate for a time machine. See more »

Goofs

Quotes

Mr. Spock: There's no further need to observe me, Doctor. As you can see, I've returned to the present in every sense.
Dr. McCoy: But it did happen, Spock.
Mr. Spock: Yes, it happened. But that was five thousand years ago. And she is dead now. Dead and buried. Long ago.

THIS SHOULD HAVE BEEN THE LAST EPISODE!
27 October 2018 | by zitacarnoSee all my reviews

After watching this episode several times I have come to the conclusion that this should have been the series finale. It was an absorbing trip backward in time, to the different aspects of various civilizations and the various stages of evolution---such as Vulcan in primitive times, the time of so-called witchcraft and how Kirk coped with it, the trials of poor Zarabeth and how she almost escaped...and how Kirk and Co. escaped back into the 23rd century just barely in time before the sun went supernova. I enjoyed this one and have always felt that it should have been the fitting conclusion to a superb series.
