A weird but brilliant story centering around a film crew doing a documentary about Ben, a serial killer. Slowly they get drawn into his world to the point of participing in his killing.

The brilliant thing about this movie is how it will make you laugh and cheer for the protagonist (a murdering sociopath), and then suddenly turn around and make you sick to your stomach.

The part where the film crew encounters another film crew doing a documentary about another serial killer is hilarious.
