During a mountaineering activity, Peter's father resolutely cut the rope and fell off a cliff to his death in order to rescue him successfully. Due to the painful shadow in his heart, Peter (Chris O'Donnell) gave up his mountaineering career and parted ways with his sister, who was also a mountaineer. His sister was in danger when she challenged the towering K2 Peak in the western foothills of the Himalayas. The whole team was trapped in a cave on the peak. Due to the shortage of food and medicine, their lives were in danger. In order to rescue his sister, Peter risked his life and climbed the Himalayas again, starting a race against time and challenging the limits of nature.
