After suffering setbacks in the city, Song Mingchuan returns to Qing Shan Village in disgrace, only to be pressured by village chief Zhao Dahai into taking over an abandoned orchard in the back hills to settle an old debt. After unexpectedly discovering agarwood resources, he receives help from Lin Yuemei and others as he faces harassment from local bullies, price manipulation by merchants, and bureaucratic obstacles. Relying on his composure, respect for the rules, and solid evidence, he fights back and exposes Zhao Dahai's crimes, protecting the back hills. Ultimately, he leads the villagers in establishing an agarwood cooperative, developing a thriving industry that transforms Qing Shan Village from decline to prosperity, while finding both professional success and love.
