Veteran movie tough guy Mark Stevens both starred and directed in Escape from Hell Island. He plays the skipper of a Florida merchant boat who smuggles in Cuban refugees as a sideline. When a woman is killed while escaping, Stevens loses his license. He then becomes involved with Linda Scott, wife of the violently jealous Jack Donner. Donner charters Stevens' boat, intending to murder him--but it's Donner who winds up in Davy Jones' locker.
