Stardate 5943.7: Kirk, Spock and McCoy enter a time portal and get stuck in the past on a planet about to be consumed by a nova.
Beaming down to the planet Sarpeidon, which is about to be engulfed in the explosion of its sun, Kirk, Spock, and McCoy discover a huge library. The librarian, Mr. Atoz, has supervised the transfer of his race into the planet's past by the use of a machine called an atavachron. At Atoz's invitation, Kirk and Spock begin to examine various historical eras using the machine. When the captain hears a woman's scream, he leaps to her aid through the atavachron's portal, only to find himself in Sarpeidon's medieval past, where he is soon charged with witchcraft and imprisoned.
Spock and McCoy, attempting to follow, unintentionally enter Sarpeidon's ice age, where they meet a woman named Zarabeth. Spock soon discovers his emotional control is slipping, and he finds himself falling for Zarabeth while he begins to revert to the ways of his Vulcan ancestors. Zarabeth, also from the future, says that they cannot return to their original time without dying, assuming that they were prepared like she was. When they reveal that their time travel was accidental, she reveals that not only can they return, they must, or they will die.
In the medieval period, Kirk escapes and, with the aid of yet another time traveler, returns to the library. After Mr. Atoz and several of his duplicates fail to return Kirk to the past, they begin to search for Spock and McCoy, who have returned to the place where they arrived. Guided by Kirk's voice, they return to their proper time, and Zarabeth remains behind, unable to make the journey. Mr. Atoz then leaps through the atavachron to a time of his own choosing, and the Enterprise leaves the system before the sun goes supernova.
