Canyon Ambush

Agent Johnny Mack Brown is called to Border City, Wyoming, by the U. S. government and ordered to catch a gang of outlaws led by a mysterious masked man that is murdering ranchers and holding up stagecoach drivers. The female editor of the town newspaper, Marian Gaylord, and the sheriff Bob Conway, start an anti-crime campaign. Agent Brown discovers that some members of the gang actually work in town government, and even discovers the identity of the gang's masked leader.

Another entertaining b-western finds Johnny Mack Brown helping the sheriff stop a masked man and his outlaws from holding up the Stagecoach. It's the standard action-packed stuff with a fairly hectic plot. It features some stock footage taken from Montana Desperado, which also featured a mask raider. Not terribly remarkable, but it does grab one's attention.
