Lee Du-Seok publishes an autobiography describing murders he committed after the statute of limitations expires. A detective and one of the victims' mother search for the author while an anonymous person claims to be the real killer.

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.—Hancinema

In Korea, the serial-killer Lee Du-sok has killed ten women and there is another one missing that the police department believes he is the responsible for her disappearance. After fifteen years, the statute of limitation expires on his last murder and Lee Du-sok publishes a book describing each murder in details. Detective Choi, who was in charge of the investigation of all the ten murders, chases Lee Du-sok and challenges him to tell where the eleventh victim is. Meanwhile, Han Ji-Soo, who is the mother of his last victim, seeks revenge with her family and friends. The owner of a sensationalist television network invites Lee Du-sok and Detective Choi for a debate live. Out of the blue, a man with the alias "J" calls the TV during the debate and tells that he is the real killer and Lee Du-sok is a fraud. Who should be the real killer?—Claudio Carvalho, Rio de Janeiro, Brazil
