This is a real and stunning story: a Uruguayan rugby team's plane crashed deep in the Andes, and the survivors were trapped in a steep and snowy mountain ridge.Faced with the desperate situation of biting cold and extreme food scarcity, they struggled to survive on the brink of life and death with their tenacious will to survive.In order to survive, they have to make choices that ordinary people cannot imagine and challenge the limits of physiology and psychology.This is not only a fight with nature, but also a hymn of life about human nature, belief and hope.
