In this ruthless machinery that produces nothing but violence, money and lust, the sensitive Sarah tries to adapt emotionlessly. It is a long and hard process of acclimation, but eventually the business of love becomes a profession for Sarah. The power of money holds her captive.

An affair almost becomes her undoing. Sarah flees deeper into the labyrinth - onto the path of venal masochism. She becomes a whip-wielding dominatrix in the notorious Herbertstraße. Now the others are the victims, but Sarah almost loses her mind...
