This silent film from 1914 dramatizes the events of September 1913 in Carrizo Springs, Texas that led to the murder of a deputy sheriff and the capture of a group of smugglers. With the onset of the Mexican Revolution in 1910, groups from both sides of the struggle began smuggling arms and ammunition across the border separating Texas and Mexico. In September 1913, officers in Carrizo Springs discovered such a plot by a band of Zapatistas. Two of the officers—Eugene Buck, a former Texas Ranger, and Deputy Sheriff Candelario Ortiz—were captured by the smugglers during the attempt to apprehend the individuals. While Buck was eventually released by the bandits, Ortiz was killed. The two remaining officers returned to Carrizo Springs and assembled a posse of civilians, cowboys, and soldiers to capture the smugglers and bring them to trial for Ortiz's death. After a few days' pursuit and a volley of gunfire, the bandits surrendered to the posse and were transported to Frio County to face trial. Texas Governor Oscar Branch Colquitt appears at the conclusion of the film, congratulating the posse on the smugglers' arrest.
