Midnight Lace

American heiress Kit Preston (Doris Day) has lived in London for the past three months, ever since she married British financier and executive Anthony Preston (Sir Rex Harrison). One foggy day, a terrified Kit hears a high-pitched, sing-songy man's voice telling her that he will kill her soon. This threat is followed by more similar ones told to her over the telephone, including the threat of her death by the end of the month, with no one ever hearing the voice but her. Anthony wants to believe her and tries on several occasions to assist her in finding out who is making the threats. Scotland Yard also gets involved, but after hearing more and more about the calls, Inspector Byrnes (John Williams) believes that her stories stem from a neglected wife trying to get some attention. Both she and Anthony would admit to Anthony neglecting her, as he is kept preoccupied with work difficulties. Even Kit's visiting Aunt Bea (Myrna Loy) and the Prestons' neighbor Peggy (Natasha Parry) want to believe her, but their actions sometimes say otherwise. Could the caller be the seemingly-sympathetic Brian Younger (John Gavin), the foreman of the construction site next to the Prestons' flat, he who seems to know more about Kit than Kit has told him? Or could it be Malcolm Stanley (Roddy McDowall), the Prestons' housekeeper's parasite of a son? Kit must find someone who can help her before the caller carries out his threat, which is making Kit increasingly hysterical, as is her continued sighting of a man following her that she believes is the caller.
