Gillian Hills stars in the title role of this cult British drama that delves into the youth culture of the late 1950s. After wealthy architect Paul Linden (David Farrar) returns from Paris with his new wife Nichole (Noelle Adam), his wayward teenage daughter Jenny (Hills) rebels by throwing herself headlong into the London Beatnik scene. Jenny mixes with her hop-head friends in the coffee houses, bars and clubs of Soho, where smarmy strip club owner Kenny King (Christopher Lee) tries to seduce her into the glamorous dancing business. When an old friend of Nichole's reveals her dubious past to Jenny she uses the information to blackmail her new stepmother and embarrass her father. But as her behaviour grows increasingly wild and reckless the newlyweds are forced to intervene to put a stop to Jenny's unruly antics.
