Four interwoven stories that occur on Halloween: an everyday high school principal has a secret life as a serial killer; a college virgin might have just met the one guy for her; a group of teenagers pull a mean prank, and a bitter old recluse receives an uninvited guest.

After a young, middle-class couple moves into what seems like a typical suburban house, they become increasingly disturbed by a presence that may or may not be demonic, but is certainly the most active in the middle of the night.
