On April 5, 1941, a date Serbs will recognize, men on a country road board Krstic's bus for Belgrade: two Gypsies who occasionally sing about misery, an aging war vet, a Nazi sympathizer, a dapper singer, a consumptive, and a man with a shotgun. Krstic is a world-weary cynic, out for a buck; the driver is his son, the simple, cheerful Misko. En route they pick up a priest and young newlyweds going to the seaside. Along the way, mis-adventure strikes: a flat tire, a rickety bridge, a farmer who's plowed the road, a funeral, two feuding families, an army detail, and a lost wallet slow the bus and expose rifts among the travelers. On April 6, amid rumors of war, they reach Belgrade...

Group of petty criminals is trying to make some money under the disguise of musical band in Nazi-occupied Serbia.

The story follows an underground weapons manufacturer in Belgrade during WWII and evolves into fairly surreal situations. A black marketeer who smuggles the weapons to partisans doesn't mention to the workers that the war is over, and they keep producing. Years later, they break out of their underground "shelter" --- only to convince themselves that the war is still going on.
