Old diners have been offering great food and comfort to customers for decades. But many of them are in danger of closing because they don't have a successor that will keep the tradition. SUCCESSORS is a program that will solve the problem: six contenders will compete to be the successor of the old diner and inherit the very recipe. Three of them are celebrities who once were on stardom but are desperate to have a second chance. The other three also want a new start for their hard lives. The owner of the old diner will train them rigorously, teaches them A to Z of diner management, and pick one of them as the successor. The winner will get a specialized consultation for opening the first branch of the old diner in Seoul.
