In 1960, a Chinese mountaineering team embarks on an arduous and perilous mission to summit Mount Everest from its treacherous north face, a route that had never been successfully conquered. The team, driven by national pride and determination, faces extreme weather conditions and life-threatening challenges. Their climb is complicated by avalanches, blizzards, and the thin air at high altitudes, which test their resilience and teamwork. With limited resources and outdated equipment, the climbers must rely on their training, instincts, and each other’s strengths to overcome the numerous obstacles in their path.

Years later, in 1975, a new expedition is planned to reach the summit once again, led by some members of the original team alongside fresh recruits. This climb is backed by advanced technology and international support, reflecting the growing stature of China on the global stage. As they prepare for the ascent, personal histories and unresolved conflicts resurface, adding emotional complexity to the already formidable task ahead. The mountaineers' journey becomes not only a physical battle against Everest’s mighty forces but also an internal struggle as they confront their fears, regrets, and dreams. The narrative delves into themes of perseverance, sacrifice, and the unyielding human spirit.
