Paul, a divorced architect, marries Nichole, a woman from Paris. His teen daughter Jenny has fallen in with the English beatnik scene and likes to hang out in cave-like clubs to listen to jazz and rudimentary rock’n’roll. Jenny takes an immediate dislike to her step mother, who is not that much older than she, and goes out of her way to make life miserable for Nichole. When Jenny discovers that Nichole is a friend of one of the strippers from the dance hall across the street, she investigates and uses Nichole’s sordid past to embarrass her father. Meanwhile Jenny attracts the lecherous eye of Kenny, the owner of the dance hall.
