Though the film was one of Margheriti's most financially successful films, it received poor reviews from Variety and The New York Times and drew three nominations at the 1983 Golden Raspberry Awards.

It is before the dawn of time. Strange, savage beasts roam the earth, foraging for human flesh. Fierce tribesmen prey on the weak and innocent. Mystic sacrifices appease the gods. Yor (Reb Brown, Space Mutiny) is the mightiest warrior of his era. But his own past and true identity are shrouded in the mists of time. He knows he doesn't belong in this world, but his only clues to the fleeting memories of his past are the gold medallion around his neck and the beautiful priestess held prisoner in a forbidden city. Armed to the teeth, Yor sets off on a quest, ready to blast away all manner of terrifying creatures along the way.
