The police manage to track down a dangerous maniac who went on a hunt for women, but in his hideout they find only a dead body - someone got to him before the law. Just like before the rapist who was not punished. Just like before the cruel sadist. A killer of killers has appeared in the city, a man who has taken on the role of judge and executioner. However, his own motives may not be as noble as they seem at first glance, and even greater evil may be hiding under the guise of justice. Police investigator Anton Chekhovsky turns for help to consultants who have caught dangerous maniacs more than once. The only question is whether Leon Agranovsky will be able to unravel this case alone - when Anna is not around.
