Fylm I Saw The Devil 2010 Mtrjm Awn Layn - Fasl Alany | FRESH |

This begins a savage cat-and-mouse game: Soo-hyeon hunts Jang repeatedly, each time inflicting horrific injuries, then lets him go again—hoping to make Jang suffer prolonged fear and pain, not just die quickly.

Jang, however, is a monster without remorse. Between their encounters, he continues murdering innocent people, including a teenage girl and a bus full of passengers. He also recruits two cannibalistic accomplices. Eventually, Jang deduces Soo-hyeon’s identity and kills Soo-hyeon’s surviving family members—his father-in-law and younger sister.

The climax occurs when Jang kidnaps Soo-hyeon’s sister. Soo-hyeon rescues her, but Jang escapes. In the final confrontation, Soo-hyeon captures Jang and takes him to the place where Joo-yeon was killed. There, Soo-hyeon kills Jang not by direct violence but by setting a trap: he places Jang’s own parents and young son in a room, then forces Jang to watch through a window as Soo-hyeon remotely triggers a device that decapitates Jang’s family. In his final moment, Jang cries out in anguish—the first human emotion he has shown.

Kim Soo-hyeon is a top secret agent in South Korea’s National Intelligence Service. His life shatters when his pregnant fiancée, Joo-yeon, is brutally murdered by a sadistic serial killer named Jang Kyung-chul. Joo-yeon’s body is found dismembered in a ditch.

Soo-hyeon walks away, broken. He has become a devil himself, losing his humanity in the pursuit of vengeance. – If you meant "fasl al-any" (فصل العاني) or a similar Arabic phrase, it might be a mistranslation or an attempt to say "second chapter" or "explicit version." The film has no official Arabic chapter release. If you were looking for a specific scene or alternative cut, please clarify.

Driven by vengeance, Soo-hyeon takes a leave from work. Using his elite training, he tracks down Jang. But instead of killing him immediately, Soo-hyeon beats him nearly to death, then inserts a tiny tracking device into Jang’s ear canal. He releases him.
