Petersburg, 1903. The world of luxury and leisure for men, the world of fear and submission for women. Girls sell bodies, feelings, flirting and the illusion of love to men. Quite a big house. Princess Anna Konstantinovna Chubinova lives there. She is supported by thirteen girls who bring her income every day. Every morning starts the same - a report and profit calculation in front of everyone. Courtesans line up in a column in an emerald, elegant living room, and their boss goes from one to the other. One of the other girls is always present behind her, who carries a gilded tray for each of the bills. *Matushka gathers courtesans together every day to calculate the profit. She has one favorite - Ksyusha, there are girls who consistently bring money, and there is also Stesha - and she is always unlucky. *
