After returning to his hometown to start a business, Lin Chuan builds a brand of naturally grown bayberries cultivated without chemical treatments and signs exclusive purchase agreements with the fruit growers of Qingmei Village. On the first day of harvesting, villagers, incited by outside traders, collectively break their contracts, treating the fruit with chemicals and imitating his brand in an attempt to make a profit. Lin Chuan stands firm on quality control, refuses to accept the treated fruit, and preserves the evidence. In the end, the scammers are arrested, and the villagers who broke their promises suffer the consequences. He removes the troublemakers and restores order, allowing his brand to regain the market's trust.
