Synopsis
Elite assassin Mantis returns from vacation only to discover shocking news — Cha Min Gyu, the ruthless leader of MK Enterprise, is dead. Determined to leave the deadly world behind, he seeks a new life among rival contract killers. However, the past refuses to let go.
His longtime friend J, once a powerful assassin but now exiled from MK Enterprise, holds complicated emotions toward him — loyalty, bitterness, and unresolved tension. Meanwhile, legendary assassin Dok Go, Mantis’s former mentor and one of the founders of MK Enterprise, comes out of retirement to seize control of the organization. With power shifting and loyalties breaking, he attempts to drag Mantis back into the shadows.
As betrayal, ambition, and survival collide, a deadly war erupts within the assassin underworld.
