Penny (Susan Strasberg, Picnic) is a wheelchair-bound girl set to visit her father in France for the first time in ten years. When she arrives, she learns that he is away on business. She is left with her stepmother, Jane (Ann Todd, The Paradine Case), and Dr. Gerrard (Christopher Lee, The Lord of the Rings series), a friend of Pennys father who has come to visit. But when Penny continues to see her fathers corpse around the house, she enlists the help of the family chauffeur, Robert (Ronald Lewis, Mr. Sardonicus), to help solve the mystery.
