Plot summary

Kim Gun-woo earns his living delivering packages, and a rescue he performs for a pop star brings him the Model Citizen title and public attention. His old bandmate Mu-yeol gets in touch after years apart, and the two meet for a reunion. While they are together, a bomb goes off and a presidential candidate is killed. In the confusion Mu-yeol tells Gun-woo that the attack was arranged, that Gun-woo is meant to be taken for the assassin, and that he should trust nobody. Gun-woo flees the scene. Surveillance footage, fingerprints and witnesses are assembled to make him look like the killer, and he becomes a wanted man. He sets out to find the former operative whose name is on the card Mu-yeol handed him, while the hunt for him closes in.
