Matria (2014) is a Documentary film that follows my grandfather fought alongside Pancho Villa, became Master Mason, was an elected official who represented Oaxaca three times, and president of the national Association of Cattle Hands. In 1942, he formed the Legion of Mexican Fighters, a group of 100,000 cattle hands training to repel a possible Nazi invasion in Mexico. His story of success, however, held a secret that affected my family, and that I discovered while making this documentary. Currently, you can watch Matria on Amazon Video.
