In the southeastern fishing village of Yuwan in the 1980s, village woman Lin Haitang is betrayed by her fiancé Wu Jinbao, and her fish sales channels are blocked. Using neglected miscellaneous small fish and tiny shrimp, she brews milky white fish ball soup and sets up a stall at the wharf to make a living. Jiang Shubai, a young master from the provincial capital, is exiled by his grandfather to the fishing village, transforming from a delicate young man into a down-to-earth worker. Together, they forge a path, developing Haitang brand shrimp paste, resisting the suppression of the old brand Xiangfeng, and relying on craftsmanship and backbone to carve out their own career and romance by the sea.
