Lin Xiaowan, an office director at a construction site, has eaten boxed lunches for two years before accidentally discovering that the vendor, Uncle Zhou, charges her according to how he sizes her up: 30 yuan for two meat dishes and two vegetables, while workers get three meat dishes and three vegetables for just 20 yuan. She turns to a couple running a stall at the back entrance, who offer fresh ingredients at the same price and quantity to everyone and would rather throw away leftovers than serve food from the previous day. Lin Xiaowan arranges a partnership between the couple's stall and the construction site, and their business takes off. Zhou Fugui lowers his prices, plays the victim, and uses frozen meat, eventually getting his stall shut down by the health department. With nowhere left to turn, he receives a chance to reform from Lin Xiaowan. The three join forces to prepare 200 celebratory meals and eventually open the Honest and Heartwarming Boxed Meals shop together. A clear conscience earns people's trust, and nothing warms the heart like a bowl of food made with sincerity.
