The town of Kragujevac. The first days of the occupation, the first innocent victims. A Partisan squad acts near the town where dozens of enemy soldiers are killed. The command is short: for every dead German - shoot 100 citizens. On that day, a group of small shoe cleaners refused to clean the dirty boots of German soldiers. And they were taken to be shot. Kragujevac became a city of black flags and black scarf. The bells toll, it is memorial service for 7,000 executed.
