Once an infamous lawyer for taking up any case for money, Jang-su (SUL Kyung-gu) is now a terminally ill patient. His dreary time left is shaken up by the new volunteer Young-ki (CHO Jin-woong), a low-life gangster assigned to complete a court-ordered community service. Finding Young-ki's unrefined manner refreshing and authentic, Jang-su asks Young-ki to help him complete his bucket list in return of a large sum of his life insurance money. In desperate need of fast cash, Young-ki accepts the offer, but the job leads them to an unexpected ending.
