On a warm April night in Belgrade, curfew reigns. Krcun, in an apartment in Kalenegdan, instructs young people from Skopje on the orders of the Party.

With a group of prisoners, the Germans throw out the newcomers from the truck, shouting and shouting. Lieutenant Colonel Rudolf Ukmar gets out of the trailer.
