If you’re on a strict diet, you should eat cheese with butter without bread. Poor Tatyana Sergeyeva is trying to lose weight for the umpteenth time, and this morning the scales under her just collapsed! The start of the day can’t be called lucky, but then everything becomes even “more fun.” Tatyana is approached by a certain Zinaida Morina. Her son-in-law Igor has arrived for a visit—his cousin, the son of Igor’s uncle. To say that Igor was astonished would be an understatement. And Morina herself was no less surprised. She knew Igor’s father well and was friends with him, but she had never heard that the man had a brother. The guest made a good impression, spent a few days with the Morins, and then Zinaida realized: the newly made “relative” was searching their apartment. After the man disappeared following ridiculous explanations, Zinaida was very disturbed. Tatyana, of course, will unravel the tangle of secrets of this family—but will the customer be delighted with the result…?
