After a fog-bound collision at sea, four shipwrecked cruise survivors are marooned on a desert island: millionaire's daughter Sadie Patch, cynical journalist Jimmy Carrol, old-fashioned economics lecturer Professor Gibble, and the ship's stoker Pat Plunkett. Although the three men reach agreement that none shall become romantically involved with their lone female companion, Jimmy and the Professor endeavour to woo her. But Sadie only has eyes for Pat, the hard-drinking Irishman. However, her affection isn't reciprocated. After they are eventually rescued by a passing ship, Sadie wishes to marry Pat, but he refuses. After another shipwreck, Sadie is washed back up on the same island, and to her delight, so is Pat!
