When her hard-drinking father marries a much younger French woman, disaffected teen Jennifer (Gillian Hills) retreats to the seedy beat culture of underground London rock 'n' roll clubs, strip bars and hash dens. But when a leering go-go joint owner who fancies Jenny winds up dead, she realizes she may have carried her rebellion a little too far. Edmond T. Gréville directs this campy exploitation cautionary tale, co-starring Christopher Lee.
