In a Kazakh village at the beginning of Soviet power, a wealthy kulak (landowner) voluntarily denounces his opposition to the new regime and hands over his large home to be a new school for the children of the villagers. But three people in the village have difficulty believing that their class enemy is now their friend.

Don Cossack Stepan Razin vowed to take revenge on the boyars for his tortured friends. Having led the rebellious peasants, he becomes the leader of an entire army. Humiliated and insulted people flock to him from all over the Russian land.
