Hyuk tries to earn the trust and love of his younger brother, but abandonment and betrayal are hard things to forget. Things come to a head when Young-chun pulls Hyuk into doing one last gig for the gang. It happens to be the case that Officer Chul is in charge of. The three brothers meet again one final time.
