Everyone in the family urges the single mother not to hold on to the rundown shop, but Shen Yuelan only wants to give her daughter a stable home. One rainy night, she discovers that she can bring water to life with the palm of her hand, instantly turning dead fish and shrimp fresh and lively. On opening day, she sells out all her miscellaneous seafood and grits her teeth to secure a major order for 200 jin of ribbonfish, followed by a series of long-term contracts with the supply and marketing cooperative. When a typhoon causes the shop to collapse, she joins forces with others to protect all the seafood. Building trust through honesty, she works hand in hand with the dockside villagers to create prosperity together. By the seaside in the 1970s, she rewrites the impoverished fate of herself and her daughter through hard work and kindness.
