American Psycho (2000)

Patrick Bateman is a wealthy man from the family. Being young and handsome gives him advantages both in his business and social life. The dark side of Bateman's life, which seems to be caught up in a very ordinary life, is quite deep. Bateman is a mentally ill person who likes to kill people for no reason and keeps parts of the bodies he killed as souvenirs in his home. Nobody knows this except himself.
