murderer and cannibal. After explaining his situation to Tae-joo, the latter remarks that whoever is after him must be the relative of one of his victims. Kyung-chul consequently deduces Soo-hyun's identity after recalling Joo-yun's engagement ring, which Soo-hyun had put on before attacking him previously. Soo-hyun arrives and incapacitates both murderers along with Tae-joo's girlfriend Se-jung. The next day, Tae-joo and Se-jung, still unconscious, are arrested by the police and sent to the hospital. Soo-hyun's trusted subordinate arranges for Soo-hyun and Kyung-chul to evade the police and receive treatment for their wounds at a separate facility. The barely conscious Kyung-chul hears Soo-hyun and the subordinate talking about the transmitter. Soo-hyun releases Kyung-chul again, but the latter outsmarts Soo-hyun, slashing the throat of a pharmacist while stealing laxatives which he uses to remove the transmitter, then plants it on a driver at a truck stop that he viciously beats. Soo-hyun enters Tae-joo's hospital room to question him, and learns too late that Kyung-chul is going after Squad Chief Jang and his other daughter Jang Se-yun. Enraged, Soo-hyun breaks Tae-joo's jaw. Kyung-chul arrives at the house of Jang, and proceeds to brutally assault him with a dumb-bell, then kill Jang Se-yun. Shortly after, Kyung-chul attempts to avoid Soo-hyun's revenge by surrendering to the police. However, Soo-hyun drives by and kidnaps Kyung-chul right in front of the police's eyes. Taking him to the earlier warehouse, Soo-hyun tortures him, places him under the makeshift guillotine, and leaves him holding a rope between his teeth to keep the blade from falling. Though he mocks Soo-hyun, Kyung-chul begins to panic when he learns that his son and elderly parents, whom he had abandoned some time ago, have arrived and are trying to visit him. As his family opens the door despite his muffled protests, it triggers another mechanism set up by Soo-hyun that drops the blade and brutally beheads Kyung-chul in front of his family. With Kyung-chul finally dead, Soo-hyun, who was listening through the transmitter some distance away, breaks down in tears.
