Chen Haisheng, an honest fisherman, sees his marriage fall apart, losing both his family and his money. Even his own son is being forced to change his surname. At his lowest point, his blood activates a magical X-ray vision ability, allowing him to see everything beneath the ocean. Wild large yellow croakers, ornate spiny lobsters, giant groupers, and deep-sea tuna are hauled ashore one after another. He renovates his old house, buys boats, builds a pier, opens a seafood purchasing business, and establishes his own fishing fleet. His sister-in-law, Lin Xiulan, cannot stand her elder sister's decision and steps forward to become his business partner. As he fights against the monopoly and oppression imposed by cold-storage owner Zhao Jinhai, he upholds sustainable fishing rules, keeping the large fish and releasing the small ones rather than overfishing. While building his business, he also fights for custody of his son through legal channels.
