Psychological thriller. The police manage to track down a dangerous maniac who hunted women, but in his shelter they find only a dead body - someone got to him before the law. As before the rapist who was not punished. As before the cruel sadist. A killer of killers appeared in the city, a man who took on the role of judge and executioner. However, his own motives may not be as noble as it seems at first glance, and even more evil can hide under the guise of justice. Police investigator Anton Chekhovsky turns to consultants for help, who have repeatedly caught dangerous maniacs. The only question is whether Leon Agranovsky will be able to unravel this case alone - when Anna will not be there.
