Amidst a sea of late-1950s psychological westerns, The Phantom Stagecoach is almost refreshingly old-fashioned. The plot is motivated by an ongoing war between two rival stagecoach firms. Stagecoach owner Joe Patterson (Frank Ferguson) is as honest as the day is long, which is more than can be said for his competitor, Martin Maroon (Hugh Sanders). Using an armored stagecoach, Maroon sabotages Patterson's operation, never leaving behind any evidence that can be traced back to him. Operating undercover, Wells Fargo agent Glen Hayden (William Bishop) tries to put an end to Maroon's skullduggery, and along the way he falls in love with the villain's innocent niece Fran (Kathleen Crowley). Some amusing moments are provided by those grand old troupers Percy Helton and Maudie Prickett, while Richard Webb, TV's Captain Midnight, is cast against type as a reluctant baddie.
