Based on true and tragic events in the life of Vitaly Kaloyev, an architect and family man. In 2002, his wife and children die in a mid-air collision along with 70 other people, mostly children. The blame is put on the company responsible for monitoring the airspace, as well as the lone air traffic controller on duty at the time. Two years later, after much-obstructed efforts to get apologies and answers, Kaloyev flies to Switzerland to obtain justice.
