Lin Tianfan, a seafood buyer, sincerely visits Bihui Village and offers to purchase all its rice paddy crabs in cash at a price higher than the market rate. He even prepares a long-term cooperation contract. However, villager Li You deliberately twists the retail price of supermarket gift boxes to stir up greed among the villagers and persuade them to tear up the agreement, while village chief Zhang Wang secretly turns a blind eye and accepts benefits. The villagers insist on selling the crabs themselves. Unfamiliar with cold-chain transportation, they lose large quantities of crabs when they suffocate and spoil during transit. Without the required licenses, they cannot sell their remaining stock. Desperate, they take the risk of making unlicensed crab paste from spoiled crabs, eventually causing a food poisoning outbreak. The village loses all credibility and is blacklisted by the entire industry. With nowhere left to turn, the villagers collectively kneel outside Lin Tianfan's production base, begging him for forgiveness and help.
