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.

In the near future. Many things are like today, one thing isn't: The number of terror attacks has increased so rapidly that any gathering in public is prohibited. Any form of culture and most of human interaction is mediated by an electronic device. The psychologist Claire decides to break the isolation and plans a secret concert with her brother Aurel, a famous trumpet player who has performed concerts in front of virtual audiences only for years. Supported by the hackers Ada and Maximus, their plan seems to succeed. Things go well. Until something else starts to go deeply wrong.
