Lin Chuan, a top aquaculture technician, saves the fish in every pond across the town, only to have his hard-earned results stolen by the unscrupulous businessman Zhou Qiming and be betrayed by the entire village. When his daughter Xiaoman falls seriously ill, he desperately borrows money from everyone he can, only to be beaten and driven away. With nowhere else to turn, he is hired for a huge sum by Xu Ruotang, chairwoman of Ruotang Aquaculture. When every fish in the town's ponds dies because of the unscrupulous feed, the villagers collectively kneel before him, begging him to save their livelihoods. Lin Chuan coldly refuses. When you drove me away back then, did you ever think this day would come?
