To save the three-cent-per-catty brokerage fee, the fishermen of Xiabi Bay decide to stop relying on their middleman, Lu Haisheng, and deal directly with the seafood buyer, Shao Tiancheng. At first, everyone believes that cutting out the middleman will bring them greater profits. However, once they begin managing everything independently, problems arise at the wharf, including competition for loading trucks, mixed crab shipments, and chaotic supply scheduling, resulting in considerable losses for the fishermen. Meanwhile, Lu Haisheng keeps his promise and takes over the difficult-to-manage Luhua Port, gradually bringing order to its scattered supplies. After learning a hard lesson from reality, the fishermen of Xiabi Bay finally recognize the value of Lu Haisheng's years of coordination and logistical work. When the fishing season ends, they personally visit him to make amends. With the arrival of the next fishing season, they invite Lu Haisheng back.
