Seventeen-year-old Olga, who has decided to get rid of an unwanted pregnancy, is transported from 2005 to 2024 and finds herself in the body of herself, a thirty-six-year-old single mother. It's as if the school director, Olga Vasilevna Glagolina, has completely forgotten everything that happened to her over the past 19 years, and now behaves like a seventeen-year-old brat from the early 2000s. Olga dreams of returning under her mother's wing and continuing to enjoy her carefree youth, but she is stuck in 2024. She cannot cope with the role of the former Olga Vasilevna Glagolina, the strict director and domineering mother of eleventh-grader Ivan. Ivan, having lost his mother's control, gets the opportunity to realize his wildest dreams. But it turns out that someone must take on the burden of responsibility for the family.
