Confession of a Murder (2012)

Confession of Murder is a 2012 South Korean action thriller film starring Jung Jae-young and Park Si-hoo and directed by Jung Byung-gil. It's about a cop who's troubled by the fact that he failed to apprehend a serial murderer 15 years ago, and who returns to the case after a novelist publishes I Am the Murderer, claiming responsibility for the killings.

When the protagonist of a serial murder case 15 years ago reappears with his autobiographical sketch, 'I Am the Murderer,' therefore offering a written confession enough to catch or kill him, a repentant police officer has an opportunity to redeem himself. With subtle moments of passion and seductive elements of spine-chilling drama, Jung Byung-Gil manages to saturate his narrative. This action-thriller is elevated to a must-watch sanctuary because of the actors and clever directing.
