Lured by a gigolo, wealthy women studying ballroom dancing are blackmailed for all they’re worth as “Dancing in the Dark” on “Charlie’s Angels.” The lonely widow of a Baseball Hall of Famer is blackmailed after a short affair with a gigolo she met at her dance classes; Charlie’s Angels are called in to investigate. Jill masquerades as a disco-dance instructor, Sabrina as a rich but socially inept heiress and Kelly as a replacement photographer, supposedly sent by the blackmailer’s shutterbug. When Sabrina succumbs to the gigolo’s charms, Kelly photographs; Bosley even shows up as the irate but blackmailed father. All goes well until the real photographer returns unexpectedly and exposes them all! Kate Jackson, Farrah Fawcett and Jaclyn Smith 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.
