A group of adventurers compete with one another to find the missing heir Rene Marechal, thought to be near Tahiti. Major Owens, a middle aged Englishman with a shady past, discovers the island on which Marechal lives but is murdered by the criminal Mougins.
Mougins sets out for the island with Colette, a night club singer who is Marechal's former mistress. She is rescued by Jean, who had earlier helped Colette stow away on the boat to Tahiti. Jean and Mougins fight and Mougins falls overboard and is eaten by a shark. Jean and Collette decide to give up the search for Marechal and live on the islands.
