Set during the Bosnian war in the early 1990s, Luka is a mild-mannered railway clerk whose life is turned upside down, not just by the outbreak of the war, but when his wife runs off with a local musician. Then Luka's son is conscripted and eventually captured in the fighting. To recover his son, Luka is commanded to guard a pretty young Muslim nurse who will be used in a hostage swapping operation.
