Rio Grande Ranger

Bob, a Ranger, and his pal Hal, are ordered to lure Jim Sayres and his gang of outlaws across the border from Shonto into the United States. Bob disguises himself as a bandit named "Smoke," while Hal gets friendly with Sayres and tells him that there is a thousand dollar reward for the capture of Smoke. As Bob enters the Shonto area, he rescues Sandra Cullen and her little brother Buzzy from a mad steer and is invited to remain at the herding camp as a guest of the Cullens.
