The Mysterious Rider

The first of a long-running series of Monogram-produced westerns starring Johnny Mack Brown and Raymond Hatton that replaced the Rough Riders series following the death of Buck Jones in the Boston night club fire. Though the next three years featured Brown (as Nevada Jack McKenzie) and Hatton (in his Sandy Hopkins role from the Rough Riders series) as undercover marshals in some form or another, this initial entry had Brown as a lone rider seeking vengeance and he and Hatton's characters were unknown to each other through most of the film. Hopkins offer McKenzie a marshal's job at the end of the film, which the Brown character declined and rode off alone on his quest. This quest didn't take long as by the next film in the series Nevada Jack McKenzie was a full-fledged U. S. Marshal.

Later, Tom discovers Crowley's men rustling his cattle and is shot. Nevada finds him severely wounded and hides him with Jeff Lewis (Sam Flint) and his daughter Mary (Ellen Hall). Sandy, posing as a dentist, arrives in town after a wire from Nevada. The latter confronts Crowley with the crooked deck and also with the fact that Tom is still alive, and demands a partnership from Crowley. When Crowley learns that Lewis is hiding Tom, he decides to have both Tom and Nevada killed.
