Before Rough Riders arrive on the scene there's a killing that wasn't supposed to happen. However, Buck gets a letter at Red Bluff from Ma Turner (Sarah Padden), "I smell somethin stronger than rosin but I don't know what". Tim is on the scene and Ray is coming on strong. The rustling operation is bankrolled by Miller (Walter McGrail) who teams up with Hollywood's 'all time meanest villain' Harry Woods, Robert Frazer and the sheriff (Lee Phelps). Charles King,Tom London, Bud Osborne and Kermit Maynard prove that they're the best henchmen in the business. Christine McIntyre, Dennis Moore and Milburn Morante as Joe the storekeeper round out a wonderful cast.
