The criminal situation in Tikhodonsk is becoming more complicated. On the highway, the family of vacationer Gusarov, who turns out to be a retired detective and friend of the head of the criminal investigation department Korenev, nicknamed the Fox, is brutally murdered. At the same time, thief in law Sever returns to the city, who enters the fight for the “throne” in the criminal world, but comes under suspicion of murder. Young people who formed the “Rooks” gang commit offenses and crimes. The seemingly ordinary Kalabashkin family is traveling aimlessly around the country. An experienced killer receives an order for the Fox himself. All these events are tied into a tight knot, and Lieutenant Colonel Korenev finds himself in the center.
