The international success of the film Das Boot by Wolfgang Petersen made U-96 one of the most famous submarines in cinematic history. But the true story of one of Hitler's most fearsome U-boats and its crew goes far beyond fiction. For the first time, this documentary sheds light on the reality behind the fiction through exclusive interviews with the makers and actors of Das Boot, as well as the last survivors of the time. In doing so, this documentary explores how Hitler's propaganda images may have influenced the visual and narrative force of Das Boot.

In 1981, a film about the misadventures of a German U-boat crew in 1941 becomes a worldwide hit almost four decades after the end of the World War II. Millions of viewers worldwide make Das Boot the most internationally successful German film of all time. But due to disputes over the script, accidents on the set, and voices accusing the makers of glorifying the war, the project was many times on the verge of being cancelled.
