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.

This quest didn't take long as by the next film in the series Nevada Jack McKenzie was a full-fledged U. S. Marshal.
