Rich widows and widowers are hypnotized into thinking their deceased spouses still manage their business affairs from the 'other side' as "The Seance" airs on "Charlie's Angels." A spirited dowager, pressured by insurance investigators about the repeated disappearances of her jewelry, hires Charlie's Angels to solve the mystery. The girls get their first clue when the daffy old lady tells them that her dead husband manages her business affairs from the grave through a medium named Madame Dorian. Kelly assumes the identity of a rich Texas widow; Jill becomes her friend from the 'Lone Star' state and Bosley, their French chauffeur. Unbeknownst to the others, Madame Dorian's male assistant hypnotizes Kelly as he had done with previous widows -- to get financial information from her. During the trance, she reveals her true identity as a private investigator. Realizing that the con game has been uncovered, he programs Kelly to perceive Jill as a childhood "bogeyperson," so he can attempt a getaway. The hypnotized Kelly helps in his escape by keeping Charlie's team busy trying to stop her from killing Jill. Kate Jackson, Farrah Fawcett and Jaclyn Smith star as the Angels, Sabrina Duncan, Jill Munroe and Kelly Garrett, respectively, who work for Charlie, an unseen and very sophisticated boss who phones in their instructions. David Doyle stars as Bosley, Charlie's harried assistant.
