Dozens of people from Copiapo, Chile, work in the San Jose mine. The owner ignores the warnings of the failing stability of the mine, which collapses a short time later. The only path inside the mine is completely blocked, and the thirty-three miners manage to get to the rescue chamber. They discover that the radio is useless, the medical kit is empty, the ventilation shafts lack the required ladders, and there is very little stored food. Mario Sepulveda becomes the leader of the miners, dividing the foods rations and stopping the outbursts of violence or despair.
