Kit and Nika are investigating the death of lawyer Ilya Sologub, who was poisoned at an award ceremony after he secured the acquittal of actor Artem Martynenko. They find out that the killer is a doctor, Anna Blinova, who was taking revenge on Martynenko and Sologub for the death of her friend, a pediatrician. Kit understands Blinova's motives and decides not to arrest her, facing the question of the limits of justice.

Kit is accused of a brutal attack on the comedian Vasya Mirny: there is a witness and his fingerprints are found on the victim's backpack, and the victim turns out to be at death's door. Nika is offered to replace Kit as the main star of the media cops, but to do so, she must publicly denounce her partner. Vasya dies in the hospital, and Kit's situation becomes even more difficult.
