During World War II, Germany invented a submarine that disappeared without a trace and was invincible in naval battles. Once, the submarine was ordered to attack the British fleet. When they returned home after completing the mission, they encountered an unprecedented crisis. Potential crises threatened the lives of officers and soldiers on the ship at any time. This seemingly powerful and cold behemoth was completely unable to protect itself and could only leave everything to fate... The film was adapted from the best-selling autobiography of war correspondent Buchheim and was nominated for six Academy Awards in 1982. Wolfgang Petersen became the first person to be nominated for Best Director for a German-language film.
