Despite no hype or big stars, the thriller gave a strong performance in the ratings, ending its run at 22.1% (number one in its timeslot). Its rise in popularity was based on the tightly written and well-structured storyline, solid direction, and cast members' acting skills.

He later discovers his daughter's death was the result of a conspiracy led by politician Kang Dong-yoon, to secure his political future as a presidential candidate. Hong-suk goes from loving, doting father and cop to harrowed man hellbent on revenge, as Kang continues to rise in power. With the help of Kang's sister-in-law, a reporter, Hong-suk takes revenge against the man who ruined his life.
