Manyang is a small town on the outskirts of Seoul and is usually quite mundane. Dong Sik, a police officer who works at the substation there, is known by the nickname, "the nut case". One day, Ju Won, an elite officer from Seoul, arrives in town. Dong Sik and Ju Won couldn't be any more different, but they end up becoming partners. Then, a skeleton appears before them.
