The Pink Lagoon: A Sex Romp in Paradise 1984

Once you enter in... you're in paradise

Directed by Svetlana

A group of models/actresses return to a picturesque tropical island to rescue the wrongfully convicted man who had saved them when they were stranded there. While exploring the island, they meet caveman-like natives who initially seem aggressive. When the natives realize the women are amenable to relations, they become friendlier.
