Chen Jiao, an ace fishing captain, risked his life to catch a million-dollar tuna for the Song family's fishing fleet, yet received only a meager base salary while enduring years of harsh exploitation from his employers. Determined to strike out on his own, he sets up an independent operation with his wife, Song Qiao, and his brother, A Dun. Sailing a small fishing boat into the dangerous waters of Sunken Ship Cove, he repeatedly lands premium catches thanks to his exceptional ability to read ocean currents, securing lucrative supply contracts for high-end seafood. He humiliates his unscrupulous former employers and ultimately leads the establishment of a fishing cooperative, guiding fellow fishermen toward lawful business practices and a prosperous life together.
