Modern emergency physician Shen Yan wakes to find himself the illegitimate son of the Shen family clinic in Bianjing, Northern Song. The Jin army is marching south, and a storm of snow is about to fall on the capital. Someone has secretly switched the city defense maps, while the granaries, medical supplies, and military camps are all rife with danger. Shen Yan cannot save the collapsing Great Song, but on the eve of the Jingkang catastrophe, he hopes to save the nameless people left out of the history books. The clinic, the city defenses, the famine, the plague, and the royal family's escape: as the heavy snow falls, Bianjing's fate is pushed toward the abyss.
