Bosnia, 1992. Luka, a Serbian engineer from Belgrade, has installed himself in a village in the middle of nowhere with his opera singer wife, Jadranka, and their son, Milo. Luka is preparing to build the railroad that will transform the region into a tourist's paradise, connecting Bosnia to Serbia across Podrinje. Utterly engrossed in his work and blinded by natural optimism, Luka remains deaf to the increasingly persistent rumblings of war. When the conflict explodes, Luka's life is turned inside out. His wife Jadranka disappears on the arm of a Hungarian musician while his son Milo is drafted. Ever optimistic, he waits for his family to return, but Jadranka doesn't come back. Milo is taken prisoner and the Serbian Army appoints Luka guardian of Sabaha, a Muslim hostage. Before long, Luka has fallen in love with Sabaha but the young woman is destined to be handed over in exchange for a Serbian captive: his son Milo. Luka passes with Sabaha through an adventure until the trade momentum, after which the two are reunited after the peace.
