The story of the film is based on real historical events. The most famous crimes from the mid-eighties of the last century to the present day have been used as the basis for the detective plots of the picture. The main character, Oleg Krainov, after serving in the army, comes to Moscow to enroll in the acting department at VGIK.

As a result of mysterious circumstances, seventeen-year-old Olga from 2005 finds herself in 2024 in the body of herself, but already a thirty-six-year-old single mother. Having no experience of adult life, Olga behaves like a frivolous girl from the noughties, and dreams of returning to a carefree youth. But by the will of fate, she is forced to take responsibility for her high school son and play the role of a school principal, which she is completely unprepared for.

Lyubanya, a hairdresser who has lost her job, and her eleven-year-old son find themselves in a difficult situation. She tries to borrow money from his girlfriend Simkina. She agrees to help, but only on the condition that Lyubanya will help her regain the man she loved, a certain Valeriy. Lyubanya must "accidentally" get acquainted with him and pretend to be his ideal, and when he falls in love with the "woman of his dreams" — leave him. Then Simkina will appear to "glue" Valeriy's broken heart, and at the same time their broken relationship. Out of desperation, Lyubanya joins in this game, but very quickly realizes that she has fallen in love. The heroine faces the question: how to tell Valeriy the truth about himself and their "casual" acquaintance?
