from the MTV website:
- From executive producer Ashton Kutcher, Room 401 is a mind-blowing journey through the weird and shocking world of illusion. Unsuspecting victims are swept into the middle of a real-life horror movie that's playing out right in front of their eyes. From the dead rising from the grave to messy chainsaw mishaps to electrifying salon encounters, these onlookers won't believe what they're seeing. Or will they?
