Miss Dors plays the sadistic Madame Margareta, an aging hooker who serves as ring-mistress of a kinky erotic stage show that features her gorgeous young nieces Susanna and Karen. They have their share of quirks, Susanna lives in a fantasy world where she impersonates different characters, and Karen is a disappointment to the johns who bid on her. One day while posing as a Russian ballerina, Susanna meets a nice airplane pilot named Peter in the park. He turns out to be a mere cargo clerk at the airport. Karen finds solace in arms of a well-to-do socialite, and neither man knows what the gals really do for a living. Margareta manipulates and pushes her nieces to greater heights of perversion for her sick client’s pleasure, until each girls takes charge of her future.
