A young girl was found murdered in a hotel room. Judging by the handwriting, this is the work of a maniac - "Hotel Chekatilo" Konstantin Revenchuk. But he is in a colony, serving time for five similar murders. Georgy and Irina understand: either Revenchuk has an imitator, or someone is trying to work to justify the maniac. It becomes known that the deceased often visited a lesbian club. The next visit was just before her death, and witnesses recall that that evening the girl met some unknown lady and left with her.

For many years, Judge Chernov and his secretary Alla Kipreeva were connected by far from official relations. The talented subordinate not only brightened up the leisure of her boss, but was also the author of most of the scientific works, thanks to which Chernov received both a degree and a place in the jury. But at one point it all ended: Alla was found dead in the entrance of her lover's house.

Poluyanov's father and son were killed. In the course of the investigation, it turns out that Sasha Poluyanov, along with other boys, attended Andrei Maslov's recording studio. But Georgy and Irina are unable to talk with the rest of the guys: someone moved to their father, someone to other relatives. It seems suspicious to detectives that too many children from Poluyanov's school have abruptly changed their place of residence. And soon they find the bodies of children, according to the descriptions, similar to the missing boys. The parents are scared and refuse to cooperate with the investigation. It becomes obvious: someone is keeping them at bay.
