Su Yang, a young man from a fishing village, takes on his family's debts and the responsibility of supporting his relatives after a family upheaval. While gathering seafood along the shore, he unexpectedly forms a contract with a whale and awakens extraordinary ocean-sensing abilities, along with an exceptional talent for identifying marine products and remarkable swimming skills. He ventures out to sea to harvest valuable seafood and resolve disputes among villagers. After meeting entrepreneur Zhao Lixuan, he establishes a coastal foraging cooperative and leads the villagers toward prosperity through hard work. Outside companies attempt to seize local marine resources and use business tactics to obstruct the fishing village's development. Su Yang joins forces with the villagers to defend their collective rights through legal means, secures a valuable partnership project, and leads the entire Dahuang Village toward shared prosperity.
