St. Petersburg, 1903. A world of luxury and leisure for men, a world of fear and submission for women. Ksenia and Stesha work in an underground brothel under the control of a handsome and ruthless lady. Girls sell men their bodies, feelings, flirting and the illusion of love. It seems that they have nothing but beauty. In fact, they have access to a secret power — the purity of the soul and the desire for freedom. And with this power, they can change everything.
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.
