For two years, Zhao Jie, who runs a convenience store in her residential community, has been collecting group-buying grocery orders for her neighbors free of charge. But after she refuses to chill Auntie Ma's drinks, Auntie Ma reports her, resulting in a 10,000-yuan fine. The groceries are cleared out and left baking in the sun, leaving piles of rotten vegetables throughout the neighborhood. Only then do the residents discover that Auntie Ma was the one who filed the complaint. As a result, Auntie Ma loses her husband's 3-million-yuan business deal, while the seafood feast at her own home turns rotten. Her husband's project falls through, and his construction crew disbands. In the end, the property management company's headquarters steps in, makes reforms, compensates Zhao Jie, and hires her to manage a new collection point. One complaint triggers a chain reaction, teaching those who take advantage of others a costly lesson while ensuring that kindness is finally rewarded.
