After graduating from university, Lin Wan and her boyfriend, Zhu Hao, partner up to establish a pig farm. However, Zhu Hao's greedy mother, Li Zhen, forces them to split up. Li Zhen replaces soybean meal with yellow mud, causing the pigs to fall ill. She then feeds them swill and injects them with hormones, eventually triggering an outbreak of swine fever. After Lin Wan's second uncle reports the farm and gets it shut down, Zhu Hao starts working to pay off the hefty fine. By chance, Lin Wan hires him back to work at her pig farm. Liu Xin, who has her eye on Zhu Hao, repeatedly interferes and slanders Lin Wan as a homewrecker. Lin Wan fights back, and Zhu Hao confesses his feelings to her, but she turns him down. A year later, Lin Wan's pig farm is thriving, and she decides to recruit her junior fellow student, Chen Yu, to help expand the business.
