Plenty of action in an adventure yarn in Bahama waters, with young Terry, captain of the Privateer, tangling with German spy, Nazi airmen, and a moving picture starlet. With the odds against his being able to scotch the German plot, he manages to bail up operations, so they will miss the German super-warship they are ordered to meet, and be in a battle to the death before they are saved by the U.S.N. Fast.
