A peasant in rural Russia comes to St. Petersburg to escape absolute poverty and find work at the outbreak of the First World War. He comes to stay with his friend, a Bolshevik worker who has organized a strike at his factory. The peasant betrays his friend to the factory's greedy management, leading to the arrest of the striker. Feeling remorseful at his actions, the peasant attempts to plead for his friend’s freedom, but the situation escalates and he is imprisoned without trial and sent to fight in the war. After returning from the front, the peasant joins the revolutionary fight along with the Bolshevik worker.
