In a near-future society a youth subculture of extreme violence rules the streets at night, speaking their own language, committing brutal rape and theft and taking drugs.  Fifteen-year-old Alex and his gang of droogs rampage through a dystopian future, hunting for terrible thrills. But when Alex finds himself at the mercy of the state and subject to the ministrations of Dr Brodsky, and the mind-altering treatment of the Ludovico Technique, he discovers that fun is no longer the order of the day.
