In the 1980s, in the Changbai Mountains, Shen Yanqiu, heir to the mountain-guarding tradition, upholds her ancestral teachings and opposes her sister-in-law's fraudulent practices, winning a major foreign trade order through quality. Facing the indiscriminate exploitation schemes of speculator Qian Wanjin and a siege by powerful capital interests, she joins forces with her lame husband, Gu Changchuan, to fight back and protect the forests. Qian Wanjin goes bankrupt, and Shen Yanqiu cures her husband's leg injury. Later, she withstands pressure from a southern merchants' association and a food tycoon's attempts to seize the mountains. By relying on traditional methods and rare mountain ginseng, she wins a partnership. Ultimately, investors fund road construction and sign long-term contracts. Shen Yanqiu leads the villagers in respecting nature, securing a reliable livelihood, and creating a legend of prosperity.
