After college student Li Hao returns to his hometown to help Lijiazhuang grow Wu Dali, he advances the costs and signs a guaranteed purchase contract. When harvest time comes, blinded by the prospect of huge profits, the villagers tear up the agreement and demand exorbitant prices. They even secretly add water to the medicinal herbs to increase their weight. Having prepared a backup plan, Li Hao instead partners with the honest and hardworking Liangjiacun village and successfully fulfills a supply contract with a liquor factory. Meanwhile, the herbs in Lijiazhuang rot and spoil, crushing the village under high-interest debt until the entire village goes bankrupt. The greedy village chief suffers the consequences of his own actions. Li Hao earns a reputation for reliability, becomes the exclusive supplier, and leads Liangjiacun to prosperity, proving that greed ultimately backfires while honesty is the key to lasting success.
