Frank (Briggs) is an unemployed, discontented and rebellious teenage Teddy Boy, living at home with his mild-mannered father (Pleasence), domineering mother (Hilda Fenemore) and sister Josie (Lynn). Frank harbours a deep-seated resentment and hatred towards the black people he sees as flooding Notting Hill and taking all the jobs. He spends his time hanging around with a gang of similar youths who all share his racist views.
