After Marshal Jordan is honored by Jimmy, Cannonball and others for his forty years as a law officer, the Sawyer mine is blown up by Belle's foreman, Kern, following Sawyer's refusal to sell out. Dan Jordan, the Marshal's son, interested in Belle, secretly the head of the outlaws, is lured by her from scouting the road on which his father guards a ore shipment. Jimmy and Cannonball drive off the outlaws, headed by Kern and Burton, but the Marshal is fatally wounded. The town council appoints Jimmy the new Marshal, which disappoints Dan, but Belle persuades him to become Jimmy's deputy, in order to get information from him about ore and payroll shipments. Dan quits as deputy and fights Jimmy when the latter suspects Belle of involvement in the robberies.
