A pharmaceutical sales rep visits a small town in Louisiana on business. He finds himself in a dark world of corruption and murder with 24 hours to live, running from the police, the mob and a sheriff that wants him dead.

Hammer Film’s follow-up to the successful One Million Years B.C. is set in an ancient past when humans and dinosaurs co-exist. Athletic cavewomen and hairy men wander around, grunting, sweating and occasionally sacrificing evil blonde babes to the sun in return for protection from stop-motion beasts. The fun-loving, energetic Sanna (Victoria Vetri), one of the sacrificial offerings, manages to escape during a ritual and joins another tribe where she says ‘necro’ a lot and falls in love with a surprisingly hairless guy.
