PLOT
Soviet provincial town on the western border. The air forces of a neighboring state attack the USSR, bombing the town. Soviet aviation is tasked with attacking enemy aircraft at its airfields. Overcoming the enemy's air barrage, three Soviet squadrons are sent to the enemy country: one to its capital, the other two to military-industrial centers. One of our bombers discovers the underground hangars of the enemy. However, the supply of bombs is running out. The commander orders the crew to parachute, and he continues to steer the plane into the opening of the last surviving hangar. Using the success of aviation, Soviet ground forces break through the enemy's front. The enemy is retreating.
