A cop from the Sheriff's department investigates a home in what at first looks like a possible break-in/murder, from the blood on the windows. Before he goes inside we know this has something to do with EVIL because a cross hanging from the rear-view mirror of the car outside turns upside-down. He enters the house, objects move from some unseen force and a man drops down from the second floor, hanging himself. There's one survivor, a woman who was the family's housekeeper. More officers show up and it's determined that the entire Anderson family -a husband, wife and two kids-have vanished.
Seventeen years later a woman and her weird son, Adrian, move into the same house. A local teenaged girl, Angela. gets a job as their babysitter because she needs the money. Her father has been laid-off work and it's hard to make ends meet. Her new employer tells her that her son has been acting odd since his father died, two years before. There's a bit more to it but that seems a good reason for his quirkiness, at first. There's also a creepy handyman who may be trouble but he's killed by a zombie dog that rips off his bottom jaw (a really good effect!). And there's an additional subplot about a group of troublesome teenaged boys who break into the house. It doesn't end well.
The best thing about this movie is that it does have an interesting twist ending, which sets it apart from typical haunted house movies. Granted, this isn't the best "haunting" movie but it's also not the worst.
