The film opens just as construction has been completed on a railway connecting a mountainous regions of eastern Bosnia and Herzegovina and western Serbia in 1992. Luka, a Serbian engineer, has moved to Bosnia from Belgrade with his mentally unstable wife, Jadranka, and his football-playing son, Miloš, to run a railway station and act as caretaker. Luka is at work preparing the opening of the railway while Miloš attempts to become a professional footballer with the Partizan team. Utterly engrossed in his work and blinded by natural optimism, Luka remains deaf to the increasingly persistent rumblings of war, which has broken out in Croatia and threatens to spread.
