When Robert intervenes, Ventnor frames him for harassing the wife. To shield her innocence, Robert stays silent, is dishonorably discharged, and becomes a sailor under an assumed name.After a shipwreck, Robert saves Iris Deane, the ship owner's daughter. While surviving on a deserted island, they fall in love. When a rescue party arrives—led by Ventnor, Iris's suitor—Ventnor tries to discredit him. However, the Colonel's wife confesses the truth back in Singapore. Cleared of all charges, Robert is restored to his military rank and reunited with Iris.
