Roman is a man who lost his wife and child in a plane crash. The tragedy happened while air traffic controller Jake Bonanos was on duty. Roman blames the air traffic controller and cannot let it go. He is demanding answers in person.
The film is based on the real-life Überlingen mid-air collision, and the subsequent murder of Danish air traffic controller Peter Nielsen at Skyguide by Russian architect Vitaly Kaloyev, who held Nielsen responsible for the deaths of his wife and two children in the disaster.
