When the law fails, vengeance becomes the only truth. Shin is a monster who tore through the lives of countless families, leaving a trail of devastation across South Korea that can never be erased. Ji-Hu Seo knows this pain all too well, having lost his father to Shin’s senseless cruelty. But he isn't alone in his suffering. Enter Du-Seok Kim, a disgraced former detective whose own family was annihilated by the same killer. Haunted by the reality that the death penalty is nothing more than a ghost of the past, these two men forge a dangerous pact. They don't want a trial or a courtroom verdict; they want blood. Du-Seok takes Ji-Hu under his wing, training him to become a lethal weapon with one singular, terrifying purpose: to infiltrate the prison system and execute Shin with their own bare hands. This is a visceral descent into the dark heart of retribution, where the line between justice and cold-blooded murder blurs until it disappears entirely. How far would you go to settle a debt that the law refuses to collect? Prepare yourself for a high-stakes psychological thriller that pulls no punches and questions the morality of vengeance itself.
