The Barber

The Barber is a 2001 film that examines the interaction between the mind of a psychopath and the minds of ordinary people who are fascinated by them. It tells the story of local barber (and serial killer) Dexter Miles (Malcolm McDowell) in a town in Alaska. The geographic location features 24-hour darkness, which serves as a metaphor for psychological darkness that drives Miles to go on a murderous rampage. —wikipedia
