Han-soo (Sung-min Lee: The Spy Gone North) and Min-tae (Jae- myung Yoo: Stranger) - who have been rivals for years - are put in charge of finding the culprit.

As cover-ups and secret deals ensue, tensions rise between the two detectives and the mounting pressure comes to a head. Also starring Daniel Choi (Traffickers), with music from the visionary composer Mowg behind I Saw The Devil and Burning. The Beast is a compelling true crime style murder mystery.
