The Siege of Leningrad has been broken. Along the narrow breakthrough corridor on the shore of Lake Ladoga, the Shlisselburg railway was built. This restored Leningrad’s connection with the mainland—but at great peril. The enemy holds the commanding Sinyavino Heights, from which they mercilessly shell trains heading into the city. Moreover, the Germans plan to encircle Leningrad once again. To prevent this, Soviet command faces an immense challenge: to push back the enemy and seize the Sinyavino Heights. The task is complicated by the terrain’s features—the steep slopes make it difficult to assess enemy defenses and effectively direct our own artillery fire.

To carry out a successful offensive, Sergeant Krutova was given a crucial mission: to advance as close as possible to the enemy frontline, establish a position there, and conduct radio transmissions reporting enemy movements. She spent eleven days in a tank under constant fire, directing our artillery fire via radio, promptly relaying information about enemy actions.

At the heart of the film lies a comprehensive interview with the heroine herself, historians, psychologists, and her granddaughter.
