After being laid off and having her engagement broken off by her fiancé, Zhou Wan, a former supply chain manager, returns disheartened to her hometown of Bailin Island. Faced with the struggling fishing cooperative and the limited market for traditional seafood craftsmanship, she decides to run for cooperative chairperson, pledging to increase revenue tenfold. She hopes to find a way forward for the island through e-commerce. But the road ahead is full of obstacles. Liu Laogen, an old cooperative member, stubbornly clings to outdated ideas and obstructs her at every turn, while a rival businessman, Boss Pan, repeatedly resorts to malicious tactics to suppress her. Undeterred by the criticism, Zhou Wan leads the islanders in developing local specialties such as dried eel, eel sauce, and handmade dried shrimp. She establishes an e-commerce night school and unites the entire island. After weathering a typhoon crisis, price wars, malicious reports, and other hardships, she finally fulfills her promise.
