In La Rochelle, a port in the German-speaking port of France, a young U-boat team was built in 1941, last night in Lake See. With the border of U 96, Lieutenant Werner is a young war correspondent who is a member of the Mission Advice for his career. The boat is commanded by the captain-in-chief Hellriegel, respectively, only "Der Alte". The responsibility for the machines is based on the vocabulary of Chef Johann, who uses the "story" of the motor day and the night of love. After the first day on the Lake, the boat assignment is not much more than a ton of very difficult to cross.
