A poor fishing family is pushed to the brink by Third Master Bao, who cuts off their ice supply, dumps dirty water on them, and takes over their fishing grounds. Their fortunes change when the father rescues a little girl from the sea who can hear the ocean speak. With her guidance, they catch giant yellow croakers, discover a cold spring, set up offshore fish cages, and even catch a golden lobster in the deep sea. After an inspection, the coast guard confirms that they have not crossed any restricted boundaries and grants them a permit for protected fishing. Third Master Bao's misdeeds are exposed and he is investigated. The little girl is officially welcomed as their daughter, and the family comes to regard the sea as both their livelihood and a beloved member of the family.
