Plot In 1943 at the height of the Battle of the Atlantic, the Royal Canadian Navy Lieutenant Commander MacClain has just lost his ship and most of his crewmen due to enemy action. While accompanying a convoy, he was attacked by a U-boat with a distinctive large Iron Cross painted on the conning tower. The U-boat surfaced and machine-gunned many of the survivors. Offered duty ashore, MacClain is determined to avenge his men. He is allocated a new ship and while waiting for it to be built befriends Joyce Cartwright, whose brother Dick, an officer, was killed under his command. MacClain's new Flower-class corvette is christened as HMCS Donnacona, and soon a crew of 65, including officer Paul Cartwright, Joyce's younger brother, is assigned to the ship. Setting out as an escort to a convoy heading for England, the Donnacona comes upon the grisly sight of a lifeboat filled with dead sailors, the result of a deadly U-boat attack. In an ocean storm, his ship is separated from the convoy, but 300 miles from the Irish coast MacClain finds other lost ships that had also been separated from their escorts. The captain of the tanker Egyptian Star relays the information that he thinks a submarine has been trailing him. The small group of ships then becomes the target of Luftwaffe bombers that are chased off by a Fleet Air Arm Hawker Hurricane fighter launched from one of the escort ships. The submarines below are still the main concern and when the Egyptian Star is torpedoed and sunk, MacClain attacks, sinking a U-boat with depth charges. Another U-boat surfaces and in a running battle badly damages the Donnacona. The U-boat is damaged by deck gun fire from the corvette. MacClain attempts to ram the submarine and when it begins to dive, depth charges are fired, sinking it. As it breaks up MacClain recognizes it as the one which had machine-gunned his former crew. The
