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.
