Shen Xiaoman transmigrates to a fishing village in the 1980s, where her greedy uncle cheats her out of her dowry and forces her to marry into the Gu family to settle a debt. On her wedding day, the Gu family's fishing boat, the Haiyan, their main means of livelihood, is seized because her husband's cousin owes money. She makes a ninety-day deal with the boat's owner, Gu Changchuan, and they join forces to build a business while posing as a married couple. Starting from nothing, they develop dried fish products and gradually establish their business. She overcomes one business crisis after another and secures steady orders, refusing shortcuts that would require her to trade marriage for resources. Standing firm against relatives trying to take her profits, she remains committed to honesty and fair business practices as she gradually secures her place.
