As the hairy crab market collapses, business tycoon Wang Guohui returns to his village to repay an old kindness, promising to buy all the crabs the villagers have to offer. Just before the contract is signed, a mysterious woman named Zhou Yao barges in with the village chief's son and accuses him of being a fraud, claiming she can sell the hairy crabs for ten times the price. Blinded by greed, the villagers sign an exclusive contract with her. After charging them one fee after another, Zhou Yao uses a fake refrigerated transport truck, and all the crabs rot on the road. The villagers lose everything and finally remember Wang Guohui. He has already been secretly laying the groundwork to expose Zhou Yao's true colors step by step. In the end, the police handcuff Zhou Yao, the whole village goes viral with a livestream that brings in a flood of orders, and a stone monument is erected at the village entrance bearing the words: 'Kindness as Vast as a Mountain.'
