Jang Deuk Cheon is the chief of the crime squad. He is a kind, caring and friendly father to his young daughter. It’s a tough job and he comes from an equally dangerous past, but he never lets his family hear it. It’s the dream life, until the chief’s daughter is kidnapped. And after trying to get her back, Jang Deuk Cheon sees that one man is always involved. Actually, make that “two men.” Sung Joon is the mysterious man somehow connected to the disappearance of Jang Deuk Cheon’s daughter. Sung Hoon is his clone. Or is Sung Hoon the original and Sung Joon the clone? Or are they both clones? Are they both real? And why do they have contrasting personalities? Why is one calm and collected while committing murder while the other is literally terrified of his own shadow? All these questions don’t matter to Jang Deuk Cheon. What matters is finding his daughter. Whether that means getting through one clone or two, he will do it. But as the detective soon learns, things aren’t that simple. While one clone is a murderous psychopath that removes organs from his victims, the other is a kind soul. And both of them need each other to survive. Now it’s a battle between the forces of good and evil, and a man and his daughter are caught in the middle of the most dangerous kind of duel.
