The Carnacki Institute exists to Do Something about ghosts. When reports of the supernatural from an old village hall point to an apparently standard haunting, an elite team of Ghost Finders is dispatched to assess the situation. The team of four includes a cameraman and former Ghost Finder from the Carnacki Institute, who is there to document events as a training tool for new recruits. But things go from bad to worse when it becomes clear they are facing something far more sinister than they first anticipated. The hall harbours a dark secret, and the team must use every trick they know to try and get out of there alive.
