Hammer Film's followup to the powerful One Million Years B.C. is put in a ancient ago when dinosaurs and humans abound. Athletic cavewomen and hairy men wander around, grunting, sweating and forfeiting blonde babes to sunlight in exchange for protection from beasts. The fun-loving, lively Sanna (Victoria Vetri), certainly one among those sacrificial offerings, manages to flee within a ritual and combines the other tribe where she's says'necro' a lot and falls inlove with a surprisingly bald man.
