🧨 What is 'Mercy for None' About?
At the heart of Mercy for None is Nam Gi-jun (played by So Ji-sub), a former gangster who left the criminal world to lead a quiet life. Years ago, he made the ultimate sacrifice—cutting his own Achilles tendon—to protect his younger brother Gi-seok from the violence he once thrived in.
But peace doesn't last. When Gi-seok, now a high-ranking figure in a rival organization, dies under mysterious circumstances, Nam Gi-jun is pulled back into the shadows to uncover the truth and exact revenge. What follows is a brutal descent into betrayal, bloody alliances, and a haunting past that refuses to die.
