Do evil spirits clean house? (spoiler, if such a movie can be spoiled)
When Daniella and Harry come to the house, they both take off their coats and put them on the long horizontal table behind the sofa. When Harry is killed in the basement, she runs upstairs and grabs her keys out of the jacket but leaves the jacket on the table.
When the foursome come home from dinner, they don't think the youngsters have been there and both their coats are gone. Is that a error or are ghost into house cleaning.
