After visiting a house in Amityville, Keith finds himself suddenly transported to another realm within the home, with no way to get out. Every door he tries leads him back into the very part of the house that he first found himself in.

Archibald the Amazing, a ventriloquist nearing the end of his career, gives one final performance with his dummy, Chucklehead. After the show, he tragically takes his own life in his hotel room-but his negative energy inhabits Chucklehead, transforming the dummy into a murderous force of terror. From a class reunion to hotel staff to unsuspecting bystanders, Chucklehead embarks on a blood-soaked rampage, vowing to make it a night to remember.
