On a typhoon night, Shen Sui is struck on the head by a flying sheet of metal while trying to save her fiancé, Chen Yanzhou. She suffers a bloody head wound and loses the child she is carrying. Yet he remains in the crowd, staring at a boat full of yellow croaker, without even looking back at her. With her dying breath, she swears to Heaven that if she gets another life, she will make him pay for every drop of blood. When she opens her eyes again, she has returned to the day of her engagement. In her arms is a mysterious book left behind by her father, The Golden Sea, which can reveal fish routes. She immediately calls off the engagement, starts drying and selling fish, opens a fish business, ventures into dangerous reefs, and takes on ruthless fishing bosses. From a helpless orphan, she rises to become the queen of the fishing seas. Those who betrayed her kneel at the docks, while she commands a ship laden with golden fish, with the vast blue sea and endless horizons in the palm of her hand.
