A couple of kids in high school rent a book called the pollonomicon, from the school library in hopes to possess an ancient demon to help them combat some bullies picking on them during school. After reading from the dreaded book, the boys soon realize they are in way over there heads as the demon takes form as a rubber chicken, and goes on a violent killing spree. Hellbent on killing everything in its path, the bodies pile up, as the boys try and stop what they created.
