Two brothers, 14-year-old Basilio and 12-year-old Bernardino, work deep inside the silver mines of Cerro Rico, Bolivia. In the mines, which date back to the 16th century, it is said the devil determines the fate of those who enter. Raised without a father and living in poverty with their family on the slopes of the mine, Basilio and his brother must work to help support their family and afford supplies vital to their education. As we come to know them, we see their fears and hopes for their future, and glimpse childlike souls peeking through their stoic faces. Trusting in an ancient belief that the devil determines the fate of all those who work in the mines, Basilio believes only the mountain devil's generosity will allow them to earn enough money to continue the new school year - their only chance of escaping their destiny in the silver mines.
