It's 1987 and Patrick Bateman (Christian Bale) is living the American dream. He has a great job, he's handsome, he's athletic and has the attention of many beautiful women. However, Patrick has a dark secret that he keeps hidden from those around him; Patrick is a psychopath. Dissatisfied with this charmed life, Patrick spends his evenings prowling the streets looking for victims; whether they are his business associates or strangers he meets in passing, he makes no distinction. Cultivating his serial killer persona as much as his yuppie lifestyle, the two sides of Patrick's life soon begin to merge and he begins to wonder where one side of his life ends and the other begins.
