Ginbayashi Yoko is a top-class chef at a high-end Italian restaurant, but her life is turned upside down when the owner runs away with all the earnings, forcing the restaurant to close. With two children to support, she takes a job at a local men’s prison as a nutritionist, where her main duties involve planning monthly menus. Encouraged by the warden, she resolves to pursue rehabilitation through food, questioning whether people can truly change and what she herself can achieve. Thus begins her new challenge—aiming for “three-star prison cuisine.”
