This may be the best of the World War II era submarine warfare movies made during the war. The captain, played by the always wonderful Randolph Scott (see him in "Gung Ho") has just lost an officer on a booby-trapped German sub - and then he comes across the always beautiful and luminous Ella Raines on shore who is the resentful sister of the dead officer. Scott meanwhile has to handle her somewhat irresponsible younger brother who is a new officer on Scott's Corvette. This may not be likely in reality, but it makes for a good dramatic situation.
Some romance simmers with Scott and Raines (not too much!) before the Corvette sails. The convoy it protects and its captains from Allies all over the world is handled very well. Scott is masterful as the captain, and the battle scenes with the German U-boats are realistic and vicious. This is a gritty movie that gives a good depiction of the absolutely vital Battle of the Atlantic and the crucial role convoy escorts played in winning the war against Hitler.
