In a futuristic Britain, Alex DeLarge is the leader of a gang of "droogs": Georgie, Dim and Pete. One night, after getting intoxicated on drug-laden "milk-plus", they engage in an evening of "ultra-violence", which includes a fight with a rival gang. They drive to the country home of writer Frank Alexander and trick his wife into letting them inside. They beat Alexander to the point of crippling him, and Alex rapes Alexander's wife while singing "Singin' in the Rain". The next day, while truant from school, Alex is approached by his probation officer, PR Deltoid, who is aware of Alex's activities and cautions him.
