Patrick Bateman (Christian Bale) is the darling of Wall Street and a hot stockbroker. He is a promising young man, earning countless dollars for his clients every day. Let's just say that he is definitely a good friend who helps you manage money and collect money. The young man is well-educated, handsome and charming, and he talks humorously. However, all this is only valid during the day. When night falls, boundless darkness and terror awaken the "devil" side of Bateman's dual character. He is a devil. A devil wandering in the street in a raincoat. Bateman is lonely inside. He needs something to stimulate his cold feelings. Silent night. Bateman kidnapped one prey to his luxurious apartment, tortured it bit by bit, watched the blood slowly gush out, and the prey died painfully, and a sense of pleasure attacked Bateman. Especially sitting there, smoking a cigar leisurely, looking at the swaying bodies hanging in the room, Bateman has never experienced such palpitations and calmness. Bateman's dual personality keeps him busy all day. However, sin cannot be concealed. What will happen to a cold-blooded serial murderer? Bateman found a paradise in his heart.
