在文革时期，一名来自地主家庭的乡村青年——赵天佑沦落到了神经疾病边缘。他被迫入居赘山区柳沟河，但改革开放后，他成为当选村委会主任。 thanks to the help of the long-term worker's son, he started a thriving herbal business, turning the villagers of Tuliujie into wealthy farmers. As a self-made entrepreneur in the farming industry, Beizhentou became a prominent figure in the area.
However, the ambitious city official Wang Hualin saw the development potential in the booming herbal industry and upgraded the Tuliujie Development Zone to the Cloudwater City Herbal Industry Development Zone. He strongly advocated for further processing of herbs. Unfortunately, Wang Hualin was later corrupted by a fake Hong Kong merchant named Xiuxianghua, who manipulated him to misappropriate funds in Cloudwater City.
Taking advantage of Wang Hualin's naivety, Xiuxianghua seduced Beizhentou with her beauty and deceived the Tuliujie farmers by stealing their herbal resources. Under immense moral and legal pressure, Beizhentou was forced to confront his actions, ultimately leading to a tragic snowy night where he leaped off a cliff to end his own life.
