A TV producer is trying to get a job on a very prestigious channel. The most defenseless segment of the population in the person of a pensioner is fighting back against telephone scammers. A difficult "crust" falls into the hands of an ordinary dogsitter, fulfilling all desires without magic and sorcery. Would-be Casanova invites all three mistresses to the wedding — without conspiring, they come to take revenge on the same day. Arriving from Belgorod, the girl shoots a blog about Moscow and makes an appointment with a native Muscovite guide, but everything does not go according to plan.

The story is about a lonely pensioner Rosa Markovna, who manages to deceive a telephone fraudster.
