In 1920's Pasadena, Daisy Gumm Majesty, a spiritualist-medium to folks with more money than sense, is talked into playing Katisha in a production of Gilbert and Sullivan's operetta, The Mikado. As rehearsals progress and Daisy falls into her role, the producer's wife experiences a mysterious decline in health, a cast member claims someone is trying to kill her, and the husband of another cast-member is murdered. Knowing Detective Sam Rotondo has his hands full, Daisy turns her attention to the murder, convinced Gloria Lippincott did her husband in.
