Alison befriends the cook's son Gwyn. Together, they discover a set of dinner plates with a floral pattern, which Alison traces and forms into paper owls. Gwyn's mother Nancy is furious and demands the plates be returned. At night, Alison becomes possessed and as Roger looks in on her, she scratches his face.
