The rapid onslaught of the troops of the Soviet Army swept away the Nazis from our land. Retreating from the city of Ensk, the Germans buried an ammunition depot in one of its regions. And after fifteen years, the city is in danger again. Shells were found on the construction of a new house. Every minute they can explode, and then everything that was built with such difficulty will perish. It seems the only way out is to evacuate the population and detonate the ammunition on the spot. But captain Dudin (Oleg Strizhenov) offers to take shells out of town and blow them up there. The five best miners led by Dudin went to the fight against death. Damp earth tightly bound the carcasses of bombs, shells and mines. Greatest caution is needed, enormous endurance and skill in order to remove and remove ammunition corroded by rust. All day the city was waiting in suspense. And only in the evening, distant explosions announced the successful completion of the operation.
