The film focuses on the unsung heroes behind the “Cloud-Top Skyway,” turning its lens for the first time to the “Kaixin Ridge” signal section at an altitude of 4,200 meters, revealing the guardians of the railway system’s “nerve endings.” Through the mentor–apprentice bond between demobilized soldier Xiao Jun and veteran signal worker Yang Zhen Shan, a former railway corps member, the story connects a series of real events, including emergency rescue operations during blizzards, nighttime wolf attacks, and equipment upgrades. It portrays the perseverance and legacy of two generations of railway workers on the snowy plateau. (Source: Chinese = Douban || Translation = kisskh) Edit Translation
