Alex and his three droogs, live in a futuristic Britain void of proper law and civil protection. They do drugs, drink, skip school, and wreak havoc during the night. They beat up an old drunkard, steal cars, rape helpless women, and start gang fights in the streets. Alex, being a rather arrogant leader, is rude and disrespectful towards his other droogs, and because of this they plot behind his back against him. In their plan to rob a woman on the outskirts of town, Alex enters the house alone to unlock the door for the other. When confronted by the owner of the house he strikes her in the head in attempt to knock her out. Meeting his droogs outside he is met with a bottle being smashed over his own head, stunning him long enough for the cops to finally arrive and arrest him. It turns out the woman he struck inevitably ended up dieing from the blow and Alex now finds himself with a 14 year prison sentence. In hopes of severely shortening his sentence, Alex signs up for a new breakthrough treatment that "cures" criminals of their want to do evil. The Ludovico treatment, as it is called, consist of Alex living a very high lifestyle while twice daily being subjected to gory and hateful films full of all that is considered wrong and evil. Part of Alex's diet contains a special drug that causes him to slowly get sick as he is forced to watch these films. After a short period of time he is shown as being cured and when, in front of a small audience, he is subjected to another bullying man and a beautiful woman, he is unable to fight back or do what he would like to do, and instead is utterly paralyzed with sickness. The process stripped him not only of his evil, but more importantly and symbolically stripped him of his right to think and be free and live the life he wishes to. After being released from prison and kicked out of his home he is taken in by small group of people who want to get Alex's pitiful story out to the public to attempt to harm the current regime in time for the next election. During this process, Alex attempts suicide and fails, but because of this the doctors of the original Ludovico treatment set out to cure him. Alex awakes from his coma cured of the sickness and is finally able to think and do what he wishes again.
