A vigilante killer dances around a friendship with a no-nonsense, skilled police detective.
He was once the best assassin the world had ever known, trained since birth to be the perfect killer. But a series of people in his life were able to teach him a little bit about mercy and love, just enough that a young woman with a bright face, kind eyes, and gentle hands could tempt him to stray. He fled with her, and for ten years and two children they lived in peace. But the man who had raised him, trained him, and bet his whole future upon this perfect assassin would never forgive him.
Ten years exactly after he fled from the organization, his old boss, his father and mentor, tracked him down and slaughtered his family.
The policeman had never understood love. He ran away from home when he was young, and life tormented him until he nearly broke. The rules became his salvation. They were clear-cut, and left nothing to the imagination. Even his own broken heart could follow them. He joined the police and slowly worked his way up, a dedicated and ruthless dog, unbribable and with nothing to hold him back.
There was something about that case that caught his attention. Something in the face of the man who had just lost his whole family, a sadness so deep that it could only be called rage, mixed with an iron-hard focus.
The police never caught the criminals responsible for the murder, but the man returned to his home two months after the murder, and he seemed to have obtained some level of peace. The policeman never forgot about that look in his eyes. The man had owned a small, home cooked restaurant right near the police station, and now that he returned he re-opened it. The policeman started consistently going there to eat for lunch, and the two men eventually struck up an easy friendship.
At the same time, people were starting to turn up dead across the city. They were all criminals; rapists, murderers, thieves, gangsters, the ones the police knew about but could never touch. The policeman is convnced that the man is behind it, even though he has no evidence. The vigilante needs the information from the police to select his next kills. Both hide their deep mistrust and broken past behind smiling faces. Both hate the need to associate with the other, yet, even when they don't need to, they find themselves returning to the only other person who shares the broken rage of their own hearts.
