American housewife Katherine ‘Kit’ Preston (Doris Day) lives with Tony (Rex Harrison), her husband of three months, in London.
On a foggy day, while walking in a park, Kit is threatened by a voice that tells that she will be murdered by the end of the month.
The next day, Kit receives a phone call from the stalker and goes with Tony to Scotland Yard, but Inspector Byrnes (John Williams) believes that Kit is making up the story to get more attention from her husband.
Kit is driven to the brink of insanity by the anonymous phone calls which nobody believes, and the elevator scene is especially gripping.
It turns out Tony and his girl friend, helpful neighbour Peggy (Natasha Parry), have contrived the entire plot to drive Kit crazy with the aid of a tape recorder that either Tony or Peggy play over the phone when they make the filthy calls to Kit.
This Hitchcockian thriller was Doris Day’s last dramatic film. She continued making films for another eight years, all of which were comedies.
