In the high-altitude city of Potosi, Bolivia, thousands of miners risk their lives daily in the treacherous tunnels of Cerro Rico, a mountain that has been continuously mined for silver since the Spanish conquest. These miners, organized into private cooperatives, face extreme conditions, including thin air, dangerous dust, and the constant threat of collapse, all while clinging to the hope of discovering a major vein of ore. Their lives are defined by a blend of grueling physical labor, deep-seated superstition, and the enduring dream of a better future, as they navigate the thin line between survival and the ever-present danger of death in the depths of the earth.
