Plot

Wang-jae, an ex-gangster, chases a gang of punks into an alley and gets fatally stabbed to death. His four childhood friends reunite in nearly 20 years at Wang-jae's funeral. Up to then, each person has gone their own way: Tae-su became a Seoul police detective. Pil-ho has taken over his brother-in-law Wang-jae's business. Seok-hwan works as a debt collector while his older brother Dong-hwan struggles as a maths professor. After the funeral, Tae-su decides to investigate the murder within a week before he would return to his job in Seoul.
