Corpse Party - Realfilm (2015)

Horror Movie Lesson Number One: if you want to stay in touch with your friends, performing a binding ceremony on the grounds of a school that was demolished after a series of horrific murders may not be a great idea. Otherwise, as a group of Japanese teens quickly learn to their horror, the simple ritual may open a doorway to an otherworldly dimension where the infamous Heavenly Host High still exists, and the demonic occupants within seek to redecorate the gore-soaked and carnage-strewn halls with a new set of bloody corpses. Now, it's a brutal education in supernatural survival as the students fight both the resident spirits and each other, where the odds of graduating alive, let alone in one piece, are sliced shorter and shorter with every heart-pounding second. Japan's ultra-violent videogame and anime phenomenon becomes a shocking live action feature film as hell is unleashed at the CORPSE PARTY!
