Movie star Tony Markham is haunted by visions of a mysterious world teeming with scantily clad cave-girls and spectacular dinosaurs. When Tony gets his hands on a magic stone icon, he is transported back in time...to a land populated by mammoth prehistoric beasts, grunting cave-men, and a clan of sexy and sensuously seductive Jurassic babes who will do absolutely anything to satisfy him. They might not have fire, but these cave-girls are hot - oh so hot! - and they just can't keep their hands off Tony or their animal furs on!

Each gorgeous girl tempts Tony in the most erotic and mouth-watering ways, yet it's for the voluptuous and delectable Hea-Thor that he falls. And amidst rampaging reptiles, scheming cave-men, and steamy Stone-Age sexcapades, Tony must decide to return to the real world or remain in Dinosaur Valley where man-eating cave-girls run wild!
