In his previous life, Chen Wanghai spent twenty years as an ocean-going captain, only to fall ill from overwork and collapse on the returning fishing boat. Opening his eyes once more, he is reborn back into the year 1985 in Red Flag Fishing Village, becoming the village's laughingstock as a "useless sea lout." With his family deep in debt, his mother coughing and unable to afford medicine, his younger sister facing dropping out of school, and the whole family trapped in a dilapidated adobe house struggling bitterly. At the moment of desperation, he awakens a special talent: every day at midnight, a seafood spot is refreshed, paired with his hard-earned captain's skills from his past life in tides, ocean currents, and identifying fish schools. From then on, Chen Wanghai embarks on a path of counterattacking through beach catching.
