An ambulance, a bus and a car enter the small town of Starolessk: Kulygin appears from the first, Sanya Balabin appears from the bus, and Bim jumps out of the car, followed by Proshkin, a colleague of the cop Makar Klimov, who was hospitalized with appendicitis. Following them, Sobolev and Sotnikov come to the town. Their appearance here is not accidental: each hero received a letter from 11-year-old orphanage Pashka, in which it is written that he is the father of a little boy. Evidence of what was written are photographs of the alleged fathers with the boy's mother, whose face is covered with a heart. And since they are all decent people, one might say, real heroes, they could not ignore the fact of probable paternity, and how could they not help the boy? But the reason for sending letters is completely different. Pashka and his girlfriend Masha, who supports him in all his tricks and mischief, want to save the orphanage. The new dads will not only have to figure out who the real father of the little fighter for justice is, but also help him save the orphanage.
