Das Boot =

the long version

In autumn 1941, a German U-boat commander and his crew set out on yet another hazardous patrol in the Battle of the Atlantic. Over the coming weeks they brave the ocean's stormy waters and seek out British supply ships to destroy. But their targets travel in well-guarded convoys. When contact finally occurs, the hunter quickly becomes the hunted, and a cat-and-mouse game begins as the U-boat hides deep beneath the surface of the sea. Soon, claustrophobia becomes an enemy almost as frightening as the depth charges exploding around them. --From publisher's description.
