Representatives of the older generation of the family, Vladimir and Marina, have already fulfilled their parental duty and sent daughter Ira and son Kolya into adulthood. The couple hopes to finally live for themselves, but Marina finds out about her pregnancy. And that's at 55! In turn, Ira is already raising two children from her first marriage with her new husband, Semyon. The couple decide to go into business and open their own cheese shop, but it turns out that being sole proprietors is not so easy. As for Kolya, he's just getting married. However, the choice of the bride surprises everyone — the guy makes an offer to a housekeeper from Central Asia, Aida.
