After her husband passed away, Lin Wan took her two children to depend on her younger brother. On a stormy night, however, she was heartlessly driven out of the house by her sister-in-law Liu Meilan, leaving her to huddle in a dilapidated boat house. In the depths of desperation, she encountered a golden carp and awakened the divine sea-sense, enabling her to see through all things beneath the ocean. To pay off an accidental massive debt, Lin Wan made a living by beachcombing. While withstanding the malicious framing of Zhang Gui, she also endured the cold gazes of her relatives. Fortunately, she received help from Aunt Chen and silent protection from Lu Shiyuan at the hydrology station. Seizing the opportunity, she engaged in pearl and seafood aquaculture, leading the village women to employment. From a penniless and down-and-out widow, she clenched her teeth and forged a career, while also reaping sincere affection.
