Cartel Land is a harrowing look at the journeys of two modern-day vigilante groups and their shared enemy – the murderous Mexican drug cartels. In the Mexican state of Michoacán, Dr. Jose Mireles, a small-town physician known as “El Doctor,” leads the Autodefensas, a citizen uprising against the violent Knights Templar drug cartel that has wreaked havoc on the region for years. Meanwhile, in Arizona's Altar Valley – a narrow, 52-mile-long desert corridor known as Cocaine Alley – Tim "Nailer" Foley, an American veteran, heads a small paramilitary group called Arizona Border Recon, whose goal is to stop Mexico’s drug wars from seeping across our border. This documentary is a chilling meditation on the breakdown of order and the blurry line between good and evil.
