While researching his family's genealogy, MacGyver discovers that his family name was disgraced during the Middle Ages. He is then knocked unconscious and, not surprisingly, is transported through dreams to the time of King Arthur. Here he must confront some stubborn knights, convince Arthur that he is a friend, and set out in search of his forefathers.

MacGyver goes up against two thieves trying to steal the only print of a rare black-and-white movie, and an old silent-film star helps him.
