รายละเอียด(อย่างย่อ) In 1985, Joe Simpson and Simon Yates, both experienced mountaineers, set out to ascend the previously unclimbed West Face of Siula Grande in Peru. Though they reach the summit, a powerful storm develops and Joe suffers a badly broken leg in a fall during the descent. The pair attempt a self-rescue, deciding to lower Joe with ropes down the steep and snowy slope while an enormous storm rages on.
