The film will be a £110 million psychological thriller distributed widely in theaters and home media. It will follow a young girl who may be possessed by her murdered mother's spirit, out to get her father who committed the crime. The film aims to make audiences uncomfortable by setting ordinary domestic scenes alongside unsettling supernatural events. It will have a dark plot leaving the ending open to interpretation, and feature only a few characters - the girl, her father, and grandmother - to build mystery around their relationships and past crimes.
