Who's Singin' Over There?

On Saturday, 5 April 1941, one day before the Invasion of Yugoslavia of the Kingdom of Yugoslavia, a colourful group of random passengers on a country road deep in the heart of Serbia board a dilapidated bus, headed for the capital Belgrade. The group includes two gypsy musicians, a World War I veteran, a Germanophile, a budding singer, a sickly looking man, and a hunter with a shotgun. The bus is owned by Krstic senior, and driven by his impressionable and dim-witted son Misko.
