U.S. Coast Guard story of adventure with romantic and patriotic asides. Craig Anderson nursed a grudge against his own Service for the justified killing of his lawless father. Captain Hart is the particular factor in his grievance, and he resents the captain's daughter, Ann, and unwillingly loves her at the same time. But something bigger comes along, as two men, supplying U-boats with food, try to use Craig to their own ends -- and he follows through only so far as to trap them, clearing his name with the Service -- and winning Ann. Good enough. Rentals.
