Rhythm of the Rio Grande

Tex Regan (Tex Ritter) arrives at the Crane ranch just as Blackie (Earl Douglas) and Pete (Chick Hannon) are preparing to burn it. He drives them off, but is accused by Ruth Crane (Suzan Dale) of being in league with Pablo, the bandit, who is blamed for most of the territory's crime. Recognizing Blackie as a henchman of Jim Bannister (Tristram Coffin),Tex starts for the Bannister ranch but is captured and imprisoned. Bannister, however, sets him free. Although Bannister has never lost any cattle to Pablo, an emblem similar to those left after every raid blamed on Pablo, is found in Bannister's house. Tex, knowing Pablo to be innocent and actually only searching for the killer of his sister, persuades the outlaw to change his hide-out and then sets out to capture Bannister, the leader of the gang. But Tex is arrested as being a member of Pablo's gang and Pablo, seeing Tex with the lawmen, believes himself double-crossed.
