The propaganda documentary about the readiness of the Red Army to repulse any enemy is based on documentary shots taken during the real maneuvers of the Red Army. Armadas of tanks, immense columns of infantry, dozens of fighters and bombers, thousands of cavalry, legendary divisions of the Civil War. The film glorifies Soviet military power and shows the Soviet people what the war will be like when the imperialists attack the USSR — quick, victorious, almost bloodless.
