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.

Great episode
14 March 2019 | by lboy1971See all my reviews

One of the best episodes of TOS. Had more than just Kirk being the focal point. The interplay between Spock and McCoy was very good and definitely proves there was never any loveloss between the two. And Mariett Hartleys legs were incredible.
