Knock

Three people are rehearsing a new play, a horror. It tells the true story of Edie, a young woman in 1970s Essex, who, whilst heavily pregnant, becomes convinced that there is something malevolent in the walls of her new home and commits a horrific crime. As odd events quickly begin to plague the rehearsal, relationships fray, realities blur and stories start to mirror. Something wants in. What happens when you open the door?
