After Gleb Kaverin beat Berdyaev in the clinic, he found himself in an unpleasant situation. The police detained him for fighting and resisting arrest, and now he faces a criminal case. The head of the ROVD, Lieutenant Colonel Startseva, who is well acquainted with Kaverin, agrees to help him, but on condition that, first, he reconciles with Berdyaev. However, she has one more necessary condition. Gleb understands that it will be difficult for him to cope with the situation without the help of the police. He decides to accept Startseva's offer and agrees to all her conditions.

Gleb Kaverin, in the course of his private investigation into who the real father of Startseva's child is, is forced to communicate more and more closely with Yelagina, the head physician at the Department of reproductive Medicine. But, as luck would have it, it turned out that Yelagina was Sorokin's ex, Kaverin's enemy and rival since the days of the medical institute. Once they fought for Marina's heart and she chose Gleb. During a difficult birth, Kaverin has to calm the violent young father with his own methods. But he turned out to be the son of the local prosecutor. He started threatening Kaverin with dismissal.
