On Saturday, April 5, 1941, one day before the Nazi invasion of the Kingdom of Yugoslavia, a colourful group of random passengers on a country road deep in the heart of Serbia board a dilapidated Krstić & Son bus, headed for the capital Belgrade: two Gypsy musicians, a World War I veteran, a Germanophile, a budding singer, a sickly looking man, and a hunter with a rifle. The bus is owned by Krstić Sr., and driven by his impressionable son Miško.
