Synopsis

June 21, 1941, Brest fortress. Lieutenant Andrey Kizhevatov, Major Pyotr Gavrilov and Commissar Yefim Fomin were engaged in daily business. There was also a boy trumpeter Sasha Akimov from the regimental orchestra, who secretly smoked and selflessly loved the girl Vera. None of the servicemen knew that the next morning they would become the commanders of the last three hotbeds of resistance, and the boy was the only link between them in the stone cauldron of the first object of attack by Nazi troops in the USSR, the Brest Fortress.
