Wally (Robert Lowery) and Jinx (Guinn "Big Boy" Williams) wash up on a Pacific island, they claim their boat was torpedoed by the Japanese but really they are US agents (FBI though that doesn't make any sense) looking for Japanese military activity. Wally also discovers Tana (Margie Hart) who wants to marry him in order to escape the island...
The film is a bit of a romp, plenty of musical numbers (some of which arn't very South Sea Island-ish) and some goofy humour. The main plot about Japanese plans to invade the island thanks to Nazi collaborators can sometimes become a bit lost. The film is a vehicle for Margie Hart, the less said about her acting the better though her singing is good.
