August 5, 2010. As the small copper-and-gold San José mine collapses, trapping 33 men 700 metres underground, the entire world focuses on Copiapó, Chile. In the following 69 days after the devastating cave-in, an international rescue team tirelessly works day and night to save the trapped miners, as the families and friends of the doomed crew can only pray for a miracle. This is the story of Mario Sepúlveda and his enclosed companions, who, against all odds, had to endure sweltering heat, hunger, thirst, and exhaustion to survive in a desperate race against time.—Nick Riganas
