MURA operative Konstantin Troshin returns from the front after the victory in the Great Patriotic War and finds out that he no longer works in the police. The reason is a conflict with an influential general of the NKGB of the USSR. But Troshin cannot imagine his life without the police. He manages to get a job as a precinct officer in the most disadvantaged area of Moscow — Maryina Grove.
