Based on Neil Simon's hit Broadway play, Plaza Suite is a collection of three comic episodes set in Suite 719 of New York City's famed Plaza Hotel, each starring comic legend Walter Matthau. In the first vignette, Matthau's wife (Maureen Stapleton) discovers--on their 23rd wedding anniversary--that he's been having an affair with his secretary. In the second story, Matthau plays a sleazy Hollywood producer who summons an old girlfriend (Barbara Harris) to his room for afternoon sex. In the last segment, Matthau and his wife (Lee Grant) deal with their daughter's wedding day jitters after she locks herself in the hotel bathroom. The trio of darkly comic stories bear Simon's trademark humor, sophistication, and wry insight into the complex nature of human relationships.
