Adapted from Brett Easton Ellis's controversial novel of the same name, this film is a black social satire that describes urban life in the United States in the late 1980s. Patrick Bateman (Christian Bale) is the pride of Wall Street, a hot stockbroker, handsome and charming, with a humorous conversation. He is young and promising and makes countless dollars for his clients every day. But when night falls, the boundless terror of darkness awakens the other side of Bateman's dual personality. He kidnaps his prey one by one to his luxury apartment, tortures them bit by bit, watches the blood slowly flow out, and the prey dies painfully, and an inexplicable pleasure attacks him. His identity makes the police investigating this series of crimes never list him as a suspect, while another equally bloodthirsty killer wants to commit a more bloody case and become the real king of killers. Bateman's dual personality keeps him busy all day long. However, the crime can never be covered up. What will be the end of a cold-blooded serial killer? Will Bateman be caught?
