Выпуск 1359. Родная для бабушки, чужая для деда?

A resident of the Kemerovo region wants to establish paternity for her 12‑year‑old daughter. But the wife of the woman's former lover and his father are convinced that she gave birth to the daughter with another man. The single mother herself also admits that the presumed grandfather might end up with "nothing" in the envelope — only not because of her fault. So, whose daughter and granddaughter is 12‑year‑old Vika?
