Jenny Templeton is a young college student who discovers that things around her are disappearing. For example, her trash is empty after having filled it with her old notes and her political science book is missing and then reappears. Jenny's roommate Kathy is accused of playing a joke on her. She then realizes that not only are her study books missing but her high school year book and other items are missing as well.

Suddenly, she hears a noise in her closet and thinks someone might be inside, but when Kathy thinks Jenny is hearing things she jokingly opens the closet only to discover two weirdly-dressed people, out-of-sync and draped in light who return her pencil mug. They tell her that they didn't want to take anything that would have been missed. Apparently, the two are a pair of time travelers from 2139 and they apologize to Jenny for the inconveniences of the missing items. While they discuss how foolish they have been, they inadvertently reveal that Jenny will become the first president of Earth and she will be called "The Great Peacemaker." After the woman returns to 2139 and the man goes back in time to 32 B.C. to see Cleopatra (the woman warned him if he did this he "shan't bother coming home.") Kathy stands in shock while Jenny thinks that she maybe shouldn't cut her political science class anymore.

This five-and-a-half-minute-long episode is based on the short story "Lost and Found" by Phyllis Eisenstein. The story was first published in Analog (October 1978).

The episode was originally slightly over 8 minutes in its initial airing. However the episode was cut down (most likely for international markets) to fit into the half-hour time slot. This was even before the show was cut for syndication.
