Welcome to Helmouth Halls, the most terrifying student accommodation in the country! Five undergrad roomies - Smithy, Charlie, Simon, Flora and Thomas - are being stalked by a serial killer. Or are they? After an evening of chilling and watching horror movies to get into the spirit of Halloween, they retire to their rooms and, like most millennials, are glued to their phones. Little do they know that the body count has already started… and it’s only going to rise! Will they ever get off their group chat to investigate?
