Veteran farm director Chen Ling has deeply cultivated the pig farm for twenty-one years, but is heavily penalized and demoted by the newly arrived inspector Lin Yue according to regulations over a meal of braised pork. Over-relying on system data and ignoring frontline practical experience, the pig farm outbreaks a major epidemic with heavy losses. During his vacation, Chen Ling stays true to his original aspiration, rejects high-paying poaching, returns to the pig farm to investigate internal interest entanglements, improves regulations, promotes village-enterprise cooperation, and balances rules with reality. The erring Lin Yue awakens thoroughly, starts over as a grassroots feeder, and everyone guards the pig farm together, welcoming a warm and fulfilled ending.
