Merrill Hammond (John Howard), governor on the prison island of Caruba, is traveling with S.S. Bombay towards Australia.

Merrill invites one of the other passengers, a woman named Diana Bryce (Helen Gilbert), to stay at his place while they wait for another transport.

Diana gets to stay in a house that Merrill originally built for his wife, who died shortly after her arrival to the island.

While the four inhabitants have dinner one night, they are watched by Dan Curtis (Gilbert Roland), one of the convicts, who has been found guilty of murder.

She is appalled by this, and when Curtis has been safely stored on a ship on its away from the island, she tells him she will leave him because she doesn't love him anymore.
