Hammer Film's follow up into the successful One Million Years B.C. is set in an early past when humans and dinosaurs co-exist. Men and cavewomen wander round, perspiration, grunting and sporadically sacrificing evil babes into sunlight in exchange for protection from beasts. The fun-loving, energetic Sanna (Victoria Vetri), certainly one among those sacrificial offeringsthat manages to flee during a ritual and also combines another tribe at which she says'necro' a lot and falls in love with a surprisingly bald man.
