 Accused of a robbery he didn t commit, ex-con Jimmy Carmody flees to the island of Caribo, safe haven for crooks and criminals, and run with an iron, but fair, hand by strongman Colonel Gomez. Initially asked to join up with and help old crime buddy Rocky Crane, Jimmy opts out and instead gets an honest job at an inn run by pretty Sally Haines and her mother. Danny, Sally s wise-guy brother, is running around with his boss Rocky s wife Rita, who has just caused Rocky to be arrested by Gomez in a gun-running escapade. Rocky escapes and, jealous, confronts Danny, who manages to kill him first. Sally, who has fallen in love with Jimmy, has a dilemma on her hands as Danny, for whom she has given a false alibi to Gomez, has just planted the murder weapon on Jimmy that will land him in front of Gomez  firing squad unless she tells the truth about Rocky s death.
