Lin Yuan, a top graduate of an agricultural and forestry university, responds to the call for rural revitalization and returns to his hometown to start a business. However, village bully Zhao Dafu deliberately lets his sheep loose to destroy the carefully cultivated orchard. His ex-girlfriend, Li Yun, even abuses her authority to issue a fraudulent appraisal and cover for him. Faced with relentless intimidation from local thugs, Lin Yuan refuses to fight violence with violence. Instead, relying on his solid knowledge of agricultural science, he legally introduces the valuable economic tree species known as Qinling giant lacquer trees. Using their naturally occurring urushiol and professional expertise, he builds a defensive barrier that makes the village bully suffer the consequences of his own destructive actions.
