On her way from England to Australia the ship "Mary Jane" gets lost in a storm and capsizes in the vicinity of an uncharted island in the Pacific. The family Lindberg, Sergeant Holt, Harper a convict, the boy David and Billy, who works as a seaman and a young Englishwoman, Cathy, are the only survivors hoping to be rescued from this uncharted island.

The harmony among the castaways is disturbed when another shipwreck survivor Irving---a convicted criminal---makes it to the island.

Irving (Don Barkham) is the convict whose obsession with the idea of escaping to the Dutch East Indies disrupts life among the survivors.
