The film follows the story of that murderer Lee Do-suk, who publishes his autobiography with his murders after the case-activation process is over. Although the suspect who deals with the murders committed by Lee Do Suk 15 years ago, things are turned upside down when another killer appears. This new killer seems to make Detective Choi think about doubts about Lee Doo Suk.
The film also fills the screen with spectacular stunt work, set pieces that thrill with both insanity and absurdity, and a generous helping of tension-releasing humor.
With dark, compelling components similar to that of The Chaser and Memories of Murder, Confession of Murder feels like a great film wrapped inside of a dreadful one that suffers from disastrous editing and shoddy writing.
