Frank Sinatra makes a rare TV dramatic performance in the role of retired NYPD detective sergeant Michael Doheny. Engaging the services of Magnum (Tom Selleck) to locate a missing person, Doheny neglects to tell the detective that he is seeking vengeance against the dirtbag who kidnapped and murdered his 7-year-old granddaughter during his retirement party. Once Magnum tumbles to what Doheny is up to, he races against time to prevent the embittered detective from becoming a murderer. The audience response to this episode was so overwhelmingly positive that a followup was planned for the following season: alas, this followup was never filmed due to scheduling conflicts, and thus "Laura" represents the very last acting assignment for Frank Sinatra in any medium. ~ Hal Erickson, Rovi
