Despite the witness protection program, someone cracked down on the Borisov couple. Denis's husband badly damaged the Tambov criminal group by testifying in court about their financial machinations. During a search in the apartment of the murdered, Loginov found a fragment of a photograph of an unknown man. It seems to investigators that the bandits have nothing to do with it. Raya, the daughter of the Borisovs, unexpectedly sheds light on this complex matter.

The teenager Sasha dies in a car accident, and his mother Nina Tsareva and three younger brothers are hospitalized. Loginov and Petrovskaya interview witnesses to the incident and establish that the cause of the accident was a technical malfunction. However, the man who accidentally saved Tsareva and her sons insists on his version, according to which Nina herself wanted to commit suicide and kill her children.

The mutilated body of a certain model's Olesya Slavutich was found in the apartment miserable. The first came under suspicion of her friend - male model Alex Volkov, after a quarrel with her before the eyes of his colleagues on the podium. However, the head of the modeling agency Mironov says, the scandal was part of a planned advertising campaign. Meanwhile, the second murder is a young girl Katie. The handwriting is identical.
