Lieutenant Seo Yi-hwa goes undercover to catch a drug cartel, and his first goal is to get close to the boss, Cha Tae-gun. So far, things are going well, but when Tae-gun realizes who he is, he demands that he join him in bed. He even threatens to kill his family if he runs away. ...You're going to let him go when you know he's a cop? You're going to use him as a puppet? That doesn't make sense.

“You bastard, what do you want from me...!” "How do you think I recognized you?" "What?" "...I've never forgotten what you said to me ten years ago."

Memories of ten years ago flashed through his mind. A hellish feud resurfaces.
