A German U-boat crew experiences the terror and claustrophobia of life on a submarine in the Battle of the Atlantic. They face the constant threat of attack from enemy ships and aircraft, as well as the psychological strain of being confined in a small space for months on end.

"The Boat" is the story of the crew of one of the thousands of U-boats deployed by the Germans in World War II. Subject to countless hours of claustrophobic confinement and unending assault by enemy ships, the crew struggles for survival. (imdb)
