A ne're-do-well man, a beautiful girl, and her one-legged body-guard/family servant are the sole survivors---they think---of a ship wreck and make it to a uninhabited south-seas island. The influence of the girl brings about a reformation of the man in this version of Eden...until three sailors, also survivors, show up, and have designs on the girl. Then a pirates' treasure chest is discovered buried on the beach, and matters become even more tense...and violent.
