Zhou Shoucheng, who has been a rural banquet chef for half a lifetime, values genuine ingredients and generous portions. However, his apprentice Shao Zhiqiang snatched away twenty tables for a longevity banquet his master had already booked by undercutting prices. To make more money, he bought spoiled cooked meat and moldy dried goods. The longevity banquet poisoned a courtyard full of relatives and friends, sending many to the hospital. After the incident, instead of clarifying what ingredients he used, he tried to use his master's reputation to get through it and make his master take the blame for him. Zhou Shoucheng refused, and worked through the night to buy other groceries to save another family's banquet. In the end, Shao Zhiqiang and his supplier received prison sentences, and Zhou Shoucheng, who cooked banquets with honesty and cleanliness, won back the trust of the host family.
