Movie producer John Addison (Robert Ellenstein) ends up in deep trouble when he picks up an attractive female hitchhiker (Carol Leigh), who proceeds to shake him down for money. Addison turns to Perry Mason (Raymond Burr) for help when he is accused of murdering Edgar Ferrell (Paul Cavanaugh)--and the only witness to the crime happens to be the blackmailing girl. This episode is based on The Case of the Vagabond Virgin, a 1940 novel by Perry Mason creator Erle Stanley Gardner (the title was, of course, altered to satisfy the CBS censors!) In 1965, the same novel would be refilmed, with variations, as "The Case of the Golden Bears."
