Chen Mancang, a fruit farmer from Qingshi Village, is an expert at identifying fruit varieties and quality. An outsider merchant, Mr. He, pretends to sell the village's mountain produce through livestreams and becomes an overnight sensation. He maliciously suppresses Chen Mancang, who exposes the truth, and cuts off his supply. With the support of agricultural technician Zhou Qinghe and the village Party secretary, Chen Mancang insists on selling only locally grown produce that has ripened naturally. His rivals repeatedly resort to counterfeiting, framing him, and manufacturing supply crises. Eventually, opportunistic internet celebrity Zhao Dapeng has a change of heart and exposes the truth.
