The film is set in rural Ireland in 1920. Rachel and Edward are twins living alone in a large dilapidated country mansion. However, they do not live entirely alone; they have some tenants who have given them three rules to follow: They must be in bed before midnight, they cannot invite any strangers into the house and one must never leave the other. The Lodgers is a good old-fashioned ghost film, completely stripped of humour and ironical distance. Simply a nice horror movie.
