During a mountaineering exercise, Peter's father resolutely chose to cut the rope and fell to his death in order to allow him to be successfully rescued. Due to the shadow of pain within him, Peter (Chris O'Donnell) gives up his mountaineering career and ends up on bad terms with his sister, who is also a mountaineer. My sister was in danger once while challenging the towering K2 Peak at the western foot of the Himalayas, and the whole team was trapped in a cave on the peak. Due to the shortage of food and medicine, their lives are in jeopardy. In order to rescue his sister, Peter risked his life and climbed the Himalayas again to compete with time and challenge the limits of nature.
