The reservation authorities try to arrest the cowboys, who must shoot their way to freedom in order to uncover the real culprits--a crooked government agent and his gang. North Of The Rio Grande (71 min.) - Hopalong's brother, Buddy, has been gunned down by train robbers and his young wife made a widow. Out for justice, Hoppy rides into the town of Cottonwood Gulch posing as a notorious bandit looking to join the gang of thieves. Conspiring with the president of the railroad (a young Lee J. Cobb in his first screen appearance), Hoppy uncovers the hidden identity of the bandit leader and corrals the cunning villain.
