Beyond Evil Episode 13

Meet the two fearless men willing to go to extreme lengths in their pursuit of a serial killer that has shaken up their quiet city: Lee Dong Sik, a once capable detective, is now demoted to performing menial tasks at the Manyang Police Substation. He was just beginning to settle into a peaceful life when his new superior, Detective Han Joo Won, is transferred in. Joo Won is an elite detective whose father is the star candidate for the National Police Agency’s next chief. Despite his admirable qualities and high social standing, Joo Won harbours a long-held secret. When a string of gruesome killings occurs, a pattern takes shape that is oddly reminiscent of some cold serial-murder cases from 20 years prior. Dong Sik and Joo Won team up, vowing to stop this vicious culprit in his tracks. As their investigation proceeds, they are forced to look far deeper than what the evidence suggests, questioning the culpability of all those surrounding the case, including their own.
