The Hongcaowan paper mill was ordered to halt production due to sewage discharge issues, causing an uproar in Hongcaowan Village. Jin Cheng, the village party secretary and also director of the village committee, adopted the suggestion of Jingu, a female professor from the Agricultural University, and led the people of Hongcaowan to overcome numerous difficulties. They started an ecological pig farm and planted green crab field rice. However, in order to repay debts, Jin Cheng self-inflicted injuries on his body to争取 more repayment time, which caused a huge stir in the "case-breaking" process; Jingu invested all her family's savings into ecological agriculture without her husband's knowledge, leading to irreconcilable conflicts with her husband; Jin Cheng's wife lost her life while trying to save ChunYa, a misguided young rural woman; the ecologically-raised pigs that were ready for market failed the inspection, bringing an impending disaster to the ecological pig farm. Faced with all sorts of pressures, Jin Cheng used his sense of responsibility and wisdom to lead the entire village out of difficulties step by step. They established an ecological agriculture cooperative, implemented a new type of land operation model, and accelerated the process of agricultural industrialization and mechanization.
