The Enfield Haunting

In 1977 London, a family's home shows signs of poltergeist activity, prompting local newspaper reporters who are covering the story to ask an investigator from the Society for Psychical Research to help.

As the investigation into the haunting continues, Janet is further terrorized by the poltergeist, causing Guy - and a reluctant Maurice - to contact a medium to try and communicate with it, before their superiors are called in.

In order to rid themselves of the various investigators disrupting their lives, Janet and Margaret claim that the haunting is a fake before inviting Maurice and Guy back, who attempt to exorcise the spirits from the house for good.
