Where to watch The Gangster, the Cop, the Devil
Don't let the devil win.
After barely surviving a brutal attack by a sadistic serial killer, crime boss Jang Dong-su is left humiliated. Determined to catch the killer known as K, he forms an uneasy alliance with Jung Tae-seok, a relentless and incorruptible detective who often disrupts his illegal business. However, while Jang Dong-su wants K dead, Jung Tae-suk is determined to bring him to justice. With a deal in place—whoever finds K first will decide his fate—the hunt begins, blurring the lines between crime and law.
