Su Wanhe, a young woman specializing in mushroom cultivation, is publicly dumped by her fiancé's family. Heartbroken, she retreats to a forest ranger's cabin deep in the mountains, where she meets Lu Xun, a quiet forest ranger. Using the forest's rich humus, she cultivates wild-style mushrooms and joins forces with elderly villagers to develop mushroom sauces. Together, they break buyers' monopolies and open up online and offline sales channels. When faced with malicious price cuts, rumors, and slander, Su Wanhe clears her name through her professional expertise and honest, high-quality products. She gradually wins over the villagers' trust, establishes a mountain produce cooperative, and develops mushroom processing and forest-based picking tourism. Building a distinctive mountain mushroom industry, she leads the villagers who have stayed behind to increase their incomes and achieve prosperity. In the end, she joins hands with Lu Xun, who has stood by her side throughout, to forge a path toward protecting the mountains and achieving shared prosperity.
