Rich Sadie Patch is marooned on a desert island after an emergency on her cruise-ship. With her are Irish stoker Pat, prickly young Jimmy Carrol, and bald and bookish Professor Gibble. All fancy their chances.

In Victorian London, young Adelaide is born into luxury, but marries starving artist Henry. His alcoholism and their lack of money lead to many quarrels. During one such fight, Henry slips down a flight of stairs and dies. A neighbor, Mrs. Mounsey, is the only witness, and she blackmails the young widow by threatening to tell the cops that Adelaide killed her husband. Luckily, lawyer Gilbert swoops in to help Adelaide.
