Desc: Below the Rio Grande: Directed by Neal Hart. With Neal Hart, Charles Brinley, William Quinn, Doris Stone. Pierre Jacques, a French Canadian fugitive from justice, rules a town on the Mexican side of the border. Chuck Watson, his thieving confederate, frames Texas cowboy King Calhoun on a cattle-rustling charge. King is given a chance to prove his innocence by leading the sheriff to Pierre Jacque and Chuck. Meanwhile, the Northwest Mounted Police and the Mexican Rurales have also learned of the outlaws' whereabouts. The three-cornered chase ends in the capture of the bandits and the liberation of King, who finds romance with Pierre Jacques's adopted daughter, Jean.
