All Hallows' Eve Horror

It's that creepy time of year again...Halloween. And a group of friends have gotten together for a party at an old abandoned and haunted house where an entire family was once murdered. Seems totally safe right? Wrong. Because not only do the kids decide to play some tricks and have a few treats, they manage to revive a supernatural killer; a killer hell bent on sacrificing them one by one to evil forces possessing the home. Will anyone escape? Or will they all be slain and become permanent residents of the infamous Amityville house?
