Chen Guilan, the owner of Guilan Home-Style Restaurant, a time-honored establishment with thirty years of history, is forced out of control of the business by her daughter, Li Ting, and son-in-law, Wang Qiang, under the pretense of letting her enjoy her retirement. After taking over, the couple secretly replace the payment QR code, delay paying suppliers, substitute pre-made meals and expired ingredients for fresh produce, and resell leftover food. The restaurant's reputation collapses, diners suffer food poisoning, and the business is eventually shut down and stripped of its license. The couple loses their entire family fortune in compensation, and their marriage falls apart. Chen Guilan reopens across the street under the name Guilan Flavor. Former employees and suppliers return one after another, and the restaurant thrives again thanks to her commitment to real ingredients. With nowhere else to turn, Li Ting and her husband kneel and repent. Chen Guilan serves two bowls of hot noodle soup and tears up the IOU, bringing mother and daughter back together.
