On June 4, 1944, Captain Daniel Gallery and his crew from U.S. Naval Task Force 22.3 achieved a remarkable feat: they captured a German U-boat. This was the first enemy warship taken in battle on the open ocean by the U.S. Navy since 1815. The film follows the historic U-505, from its role as a key part of the German fleet to its current display at the Museum of Science and Industry in Chicago. It features archival footage and interviews with German and American crew members who participated in the U-505's capture, including rare footage of Captains Daniel Gallery and Harold Lange, who commanded the U-505 during the event.
