Heavy snow blankets the mountains, blocking the roads with ice and snow. Zhou Chengnian sets off on his journey home with his girlfriend, Lin Qiaowei, returning to Jiuyan Village after many years away. The atmosphere in the village is unusually oppressive, and one strange occurrence after another begins to emerge. Lin Qiaowei knows nothing of the past between Zhou Chengnian and Luo Wanqing. In this unfamiliar village, she soon mysteriously disappears amid the swirling snowstorm. Distraught with worry, Zhou Chengnian gathers Lao Qin, Mingchuan, and the others. Under cover of darkness, they resolutely enter the Shadowed Ridge, a place everyone in the village avoids, determined to search every dangerous corner and bring his girlfriend back.
