What kind of people dedicate themselves to humanitarian causes today? Why do they commit themselves, sometimes to the point of risking their lives? This film follows the odyssey of three aid workers who are transporting food to Armenia by truck: Amine, 30, who has decided to do this type of work after completing a rehab program; Papy, 62, formerly head of a trucking company who was forced into early retirement, and Jerome, 20, who has just barely come out of a stormy adolescence. Alone at the wheels of their 38-ton trucks, they spend several weeks traveling across Germany, Poland, the Ukraine, Russia and Georgia to reach Erevan. They are faced with problems which are political (e.g. check-points, transit visas, and the war in Chechnya) as well as climatic (e.g. icy roads, and crossing the snow-covered Caucasus mountains). The film lays bare the everyday reality of humanitarian operations.
