Alex is a 15-year-old living in a near-future dystopian city who leads his gang on a night of opportunistic, random "ultra-violence". Alex's friends ("droogs" in the novel's Anglo-Russian slang, "Nadsat") are Dim, a slow-witted bruiser, who is the gang's muscle; Georgie, an ambitious second-in-command; and Pete, who mostly plays along as the droogs indulge their taste for ultra-violence. Characterised as a sociopath and hardened juvenile delinquent, Alex is also intelligent, quick-witted, and enjoys classical music; he is particularly fond of Beethoven, whom he calls "Lovely Ludwig Van".
