Lala, the new daughter-in-law of Chenjia Village, is sharp, capable, and full of grit. Seeing Wang's wife nearly lose her life after giving birth to seven children, she gets inspired by fish bladders to create a protective device that helps women suffer less. Together with her husband Chen Tieniu, she withstands her father-in-law's scolding, her second aunt's reporting, and the villagers' mockery. They conquer the challenges of removing fishy odors and toxins, and open up the town market with iced raw fish and pine-smoked fish. Fuyuan Restaurant grows jealous and suppresses them by cutting off fish supplies, cutting off ice, and poisoning them. The couple joins forces to fight back and works with the police to bring the villains to justice. In the end, Lala leads the fishermen to prosperity, and their days become as fiery and bright as the sunset by the sea.
