Hul-Soo is an overzealous detective who will do everything possible to catch his suspect. He doesn't want to waste a single precious moment even to shower, and regularly dresses in threadbare ramshackle clothes. But he's just been assigned to the case of a lifetime: Transforming into an undercover runway model in 60 days. Assigned to the monumental backstage crime case simply because of his height, among the challenges Chul-soo faces is working with high school alum Ko Young-jae, who happens to be the designer. Convinced he stinks and will ruin her show, she sets him the impossible task of shedding 20 kilograms in 2 weeks. He accepts the challenge but becoming a runway model means more than just losing weight. With so much to learn in such a short period of time, Chul-soo's case turns into the biggest Project Makeover of all time!
