Joe Simpson's best-selling memoir, turned BAFTA-winning film, charts his struggle for survival in the Andes in 1985.
At the heart of the story is Joe's mental battle, as he teeters on the brink of death and despair in a crevasse from which climbing to safety seems like a near impossibility.
Alongside this is the appalling dilemma of Simon Yates, perched on an unstable snow-cliff, battered by freezing winds and desperate to rescue his injured climbing partner who hangs from a rope below him.
Survival, strength and and the power of determination are all explored.
