George Bancroft stars as a seaman who fights his rival (William "Stage" Boyd) over a Havana saloon singer (Jessie Royce Landis) who is trying to get to Rio.
But when Bancroft gets promoted to captain, sparks fly when the ship grounds in a dense fog. Bancroft is at first commended for saving the ship but is fired when they learn that Boyd sneaked the woman on board.
When Boyd ships out to Rio with Landis, Bancroft signs on with a banana boat and follows. In a raging hurricane (great sea storm effects) Bancroft commandeers the banana boat to help rescue the sinking ship Landis is on.
Bancroft is good as the rough sailor. Boyd (not to be confused with the other William Boyd) is OK as the rival. Landis, in her feature film debut) sings a couple songs and is quite good as the woman. She wouldn't make another film until 1949 and is best remembered for her "mother" roles in Hitchcock films of the 50s.
