A story of choices and survival, Das Boot explores the emotional torment of life during World War Two, and the brutal reality of living within a senseless war.

As the 40 young men take on their first mission, they struggle with the cramped and claustrophobic conditions of life underwater. Their personalities are pushed to the limit as tensions rise and loyalties begin to shatter.
