Inspired by the actual experiences of a WWII photo-journalist. Wolfgang Petersen brings the life of a U-Boat crewman authentically alive with every moment of claustrophobic and explosive terror.

Autumn, 1941: Forty-three young German sailors aboard U-96 enter the war against Britain seeking adventure, respect and heroism. For them, this voyage is for glory. For their captain, a seasoned war veteran at the young age of 30, it is a mission against enemy destroyers in a blood-red sea that can devour a ship and its crew without leaving a trace.
