For 8 years, a widower from Tyumen communicated with the child of a young mistress out of politeness, and now she demands alimony. The man's only son is sure that his father's mistress just had her eye on the inheritance. The single mother herself assures: she claimed the rights of her son after she found out that her lover had another one. Will the widower-well done and the grandfather of two grandchildren become a dad again?
