Produced by George Blaisdell for W. Ray Johnston's low-budget Rayart Productions (the forerunner of Monogram Pictures, this unusual silent western actually stars a horse, the Grey Devil of the title, played by Starlight. This magnificent steed was screen cowboy Jack Perrin's mount, and it is Perrin who appears as the nominal star of the picture. Falsely accused of cattle rustlings, Perrin goes about to apprehend the real killer. He is befriended by a wild stallion along the way, and it is Grey Devil who rescues him in the nick of time from the villain (Tom London). Perrin was actually one of the better cowboy actors of the period, although he could be overly coy in what were meant to be humorous episodes. He gets no help from veteran "comic" Milburn Morante in this film, however, which thoroughly belongs to Starlight.
