In the early 1980s, Lin Bin, a gambler, caused the death of his girlfriend Jiang Qingxue because of his cowardice. After being reborn, he decided to change his life. He used his past life memories to catch 400 kilograms of large yellow croaker to pay off his gambling debts. He used prediction and "sonar" technology to achieve a bumper harvest at sea. He was recognized by his future father-in-law Jiang Qinmin and established a direct supply channel for state-owned hotels. Enemy Wang Yong provokes a provocation, and Lin Bin sets up a trap to cause him to be in danger in a storm, and the conflict with the village chief intensifies. Faced with a bet with the Wang family on the yellow-lipped fish bladder, Lin Bin caught the sky-high price of the fish bladder, but refused to sell it because he knew the buyer was involved in a major case. The buyer wanted to buy the swim bladder the next day, severely punished the village chief and his family for burning the boat and bought it at a high price. In the end, Lin Bin became the designated supplier of the state-owned hotel and got engaged to Jiang Qingxue.
