A city that has just survived the blockade and has not yet recovered from hunger, destruction, and death. And here the Leningrad militia is waging its unequal war against the crime that covered Leningrad after the war. In this struggle, the head of the anti-banditry department, the legendary Major Kuzmin, dies. His staff faces a difficult task – to catch the elusive band of Vitya the Musician – a cruel, sophisticated killer and bandit. Here begins the confrontation of an undercover agent Rebrov, who infiltrates the gang to capture Vitya, a musician and literature teacher Danilov, by the will of fate, after an unfair sentence, who found himself on the other side of the law and lost everything: his job, wife, daughter. Trying to achieve justice, to take revenge on those who distorted his life, the literature teacher is increasingly immersed in the criminal world of post-war Leningrad, gradually turning into one of the most intelligent and dangerous criminals. He is opposed by Rebrov, the head of the anti-banditry department. Once accidentally bumping them into a train carriage, life will bring them together more than once or twice: one woman for two, one love, one city. The story of human courage, the drama of human destinies, for the first time opens many pages of the post–war history of Leningrad — harsh and cruel.
