Scott Bakula (STAR TREK - ENTERPRISE) stars as brilliant scientist Sam Beckett who, in experimenting with time travel, loses himself in a perpetual warp that catapults him into the bodies and lives of random people throughout time. While he temporarily inhabits a person's body, Sam also must solve a problem or mystery in that person's life (the solving of which triggers another jump). Continually trying to find a way to his home time, Sam has the help of Rear Admiral Albert "Al" Calavicci (Dean Stockwell), who appears in hologram form, and the supercomputer Ziggy (voiced by Deborah Pratt), which provides clues for solving each episode's mystery. This collection contains all of the episodes in the fourth season of the very popular cult series.
