Rogue of the Rio Grande

El Malo, notorious Mexican bandit, forces the Mayor of Sierra Blanca, Seth Landport, to open the safe and turn over to him 2,000 pesos, which the bandit gives a promissory note for to the Mayor. Seth rushes to the cantina where Sheriff Rankin is drinking, and the sheriff posts a reward for the capture of El Malo. El Malo informs his men of the reward. The bandit and his sidekick, Pedro, visit the cantina where Pedro resumes a former acquaintance with Dolores, while El Malo has his attention directed to a tango being performed by Carmita. El Malo pushes her dancing partner aside and finishes the dance with Carmita. Since Seths description of him is not accurate, El May visits the sheriff and promises to deliver the wanted bandit to the cantina the following night. THe following morning, El Malo and Pedro depart, and, halting their horses on a hill, view the stagecoach being held up by a trio of outlaws. THey follow the outlaws to their hideout, where they discover the leader is the trusted town-mayor Seth. El Malo tells him to be in the cantina that night. Then things get involved, including the wrath of the displaced tango partner. El Malo handles it all without breaking a sweat.
