1941 year. The Siberian carpenter Kuzma Kroykov arrived in Moscow as part of a rifle company. In a line of fighters, he walked through the streets of Moscow at night and in a village near Moscow met Varvara Oknova. Resolute, tall and beautiful, she won his heart. But soon the protracted terrible battles for Moscow began...

During the German occupation, Belarusian teacher Ales Moroz does not abandon his students, instilling in them a sense of determination and courage. One day, the students disobey their teacher and decide to avenge their parents. As a result of a failed attempt on the lives of Nazi henchmen, the children are taken prisoner. Unable to find support from the partisans, Ales decides to share the fate of his students and surrenders to the enemy, which after the war is considered treason. Only one of his students, Pavel Miklashevich, miraculously survives until Victory Day. Continuing his teacher's work, Pavel devotes his life to restoring the good name of Ales Moroz.
