ДНК S05E85 - Выпуск 644. Бабушка против внука!

The woman claims that a year ago she gave birth to a son from her friend's husband. But the man's family insists that the boy's father is not him, but a single neighbor. The alleged father of the baby is also called the married lover of a single mother. So who is the real dad of a one-year-old son and why is the alleged grandmother not happy about the "grandson" at all?
