It is 1942 and the western edge of the USSR is under German occupation. In the region, local partisans are waging a brutal battle against their foreign enemies. Sushenya, an innocent rail worker, is arrested with a band of saboteurs when a train is derailed not far from his village. The German officer decides to set him free rather than hang him with the others, but rumors of Sushenya's treason spread quickly and partisans Burov and Voitik seek revenge.
