Confession of Murder (2012)

After the statute of limitation expires on the murders he has committed, Lee Du-seok publishes an autobiography describing all his murders in great detail. Detective Choi, who investigated Lee's murders 15 years ago starts the chase once again and Han Ji-soo, who lost her daughter to Lee, pledges vengeance. Meanwhile, another killer appears, casting doubt to whether Lee is the real serial killer. The key here is how well the story juggles the truth and how solid the description of the characters' tangled relationships is.
