Sanna (Victoria Vetri), a beautiful blonde woman, is condemned to death when she is blamed for a sudden aberration of the sun. Fortunately, the girl is rescued by fisherman Tara (Robin Hawdon), a member of the nearby Sand Tribe, but Sanna's presence infuriates Tara's girlfriend Ayak (Imogen Hassall). While others run from the carnivorous dinosaurs, Tara trains one of the beasts who believes she is one of her offspring. A typhoon leaves four survivors to fight for survival in this prehistorically inaccurate science fiction story.
