About the childhood years of the hero of the Civil War, Marshal of the Soviet Union Semyon Budyonny.

A story about Bolsheviks underground in occupied Belorussia during 1918.

Semyon Primak, in the direction of the regional committee, arrives in one of the small towns of Donbas and immediately enters into battle with the chief of the mine, Chub, who, in a situation of continuous assault, plays into the hands of the Trotskyites and bandits operating in the mine. Having received moral support from the new secretary, the best 'udarnik', shockworker Matvey Bobylev implements a new method of coal mining and, contrary to the intentions of the enemy group, finds a wide response among the miners of Donbas.

Set during the 1939–1940 Winter War, the film follows a group of young women from Leningrad who volunteer for service at the front. Working as nurses in hospitals and on the battlefield, they devote themselves to saving the lives of wounded soldiers, while also taking up arms alongside the men in combat. Through hardship and sacrifice, their courage forges bonds of friendship and love that endure amid the trials of war.
