Riot on Sunset Strip (1967)
LA bad-girl (Mimsy Farmer) gets involved with a gang of drugged-out hippie scum, much to the annoyance of her policeman father (Aldo Ray).
Inspired by the real-life Sunset Strip riots, this film was the Reefer Madness of its day, and ridiculing the love and peace generation was an easy target (so all the hippies are doped-up Nazis).
