A mother with many children declares: her son was registered with the wrong man. Except the one she thinks is the boy's father has already died. The mother of the deceased man refuses to recognize the grandson without genetic examination. Is the boy entitled to a survivor's pension? Or will the boy have to collect alimony from the living official father?

The man took the eldest son from his ex-wife through the court, and four years later demanded a DNA test for the youngest. If the genetic examination confirms their relationship, he intends to take his second son for himself. That's just the ex-wife herself is sure: he deprives her of children in order not to pay alimony. Who will 4-year–old Slava stay with - mom or dad?
