Jeonghwan, once a legendary mercenary, returns under an identity no one expected—a prosecutor. His mission is to uncover the truth behind his mother's mysterious death, the tragedy that robbed him of his peace and future. To take his revenge, Jeonghwan must wield two weapons: violence for those who stand in his way, and the law for those who must be judged.
