Zhou Jianfeng and his fellow workers have eaten at Huang Dewang's canteen for ten years. Yet, simply for asking for an extra bowl of rice, they are publicly humiliated by the owner's wife, who even digs up an old bill for 18,600 yuan. Furious, Zhou leads the workers away and supports Shen Xiumei's small canteen instead. Shen insists on using quality ingredients and displaying honest prices, earning the workers' trust. Huang Dewang, however, tries to steal customers with low prices, cuts corners on ingredients, and even secretly cuts off supplies. During a crisis on a rainy night, the two stand firm and ensure that 180 workers get their hot meals. Eventually, they secure a catering contract with the construction group. Huang Dewang's misdeeds are exposed and punished, while Xiumei's canteen continues to grow.
