After marrying into the Han family three years ago, Lu Chaoshen cannot even send 100 yuan for his sick mother's medicine. His mother-in-law, Han Yulan, smashes a bowl to stop the money from reaching her. On the seawall, he opens his wounded palm, and an old seashell pendant emits a blue glow, leading him into a mystical spirit spring dimension. Its water makes seafood grow rapidly and doubles its quality. He rents an old boat from retired boat owner Qiu Dechuan and heads out to sea, rescuing a little dolphin tangled in discarded fishing nets. From then on, the dolphin Chasing Waves leads him to schools of fish. Working with Zhao Chunmei, he sells baskets of green crabs, prawns, large yellow croakers, live abalone, and sea cucumbers at fair prices, earning enough to pay 4,800 yuan and buy his first boat.
