Two men go into business supplying medical colleges with cadavers by robbing graves.

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.

Stanley is infatuated with Margaret, the statuesque waitress who works with him. He meets George Spiggott AKA the devil and sells his soul for 7 wishes, which Stanley uses to try and make Margaret his own first as an intellectual, then as a rock star, then as a wealthy industrialist. As each fails, he becomes more aware of how empty his life had been and how much more he has to live for.
