Synopsis by Hans J. Wollstein
More a whodunit than a straight Western, this Tim McCoy series entry from Columbia featured a cowboy returning to his homestead to find his brother, the sheriff, killed and the family of his girl somehow involved. Dissatisfied with the investigation by newly appointed Sheriff Ludlow (Jack Clifford), Tim O'Neil (McCoy) discovers that Jed Harmon (Frank Sheridan), the father of Myra (Billie Seward), Tim's sweetheart, is being blackmailed by Kramer (Edward Earle). Ludlow, who is in cahoots with Kramer, arrests Jed but Tim helps the old man escape. Confessing in writing to an old crime, Jed is left alone when Tim is called out on an errand. Kramer enters the room and shoots Jed, making it look like a suicide. But Tim later demonstrates how Kramer could have left the body in a room bolted from the inside. There is a final confrontation between Tim and Kramer, which leaves the villain dead and Tim with a final resolution to avenge his brother's murder. As it turns out, Jed is still alive and proven innocent in the old charge of murder to which he earlier confessed. Tim McCoy's handsome sidekick in this and two subsequent Westerns, Robert Allen, would later star in his own B-Western series for Columbia. The Revenge Rider was remade by Columbia in 1938 as Riders of the Black River, a vehicle for McCoy's successor at the studio, Charles Starrett.
