J (23), an agent who wishes to return to a normal life, is assigned one final mission by his superior: to go undercover as an illegal courier. He sneaks into the environment to take down the drug dealers. At first, J enjoys his work. However, as time goes on, he carries out his duties reluctantly. He tries to quit his job, but doubts always linger in his mind. All that pressure left J unsure of what to do, and it was his own choices that trapped him in a dangerous cycle. There was one final mission for J and it truly became his last, because everything changed when his identity was exposed during that final mission.
