Kirsten Kosinski (Anna Kristina) leaves her provincial town to work in the big city. After getting a job as a secretary, she finds herself occasionally "sellin her charms." Eventually, she becomes a full-time prostitute and feels the need to ensure the protection of a pimp to survive in this environment.

The young couple Thomas and Monika haven't done it yet, but both dream of nothing else. Their thoughts revolve around sex, whether in the porn cinema or at home in bed. But until it finally comes to a climax, the two have to experience some raunchy adventures, because the sexual revolution of the 70s was not long in coming in Germany, as this film clearly proves.
