Mercy for None

Eleven years after turning his back on a life of crime, Nam Gi-jun, a former feared enforcer for the Joowoon organization, leads a quiet life, far from the gang wars that marked his past. But when his younger brother Gi-seok, now Joowoon's second-in-command, is brutally murdered, and Gi-jun returns to a world he thought he had left behind forever.

Determined to uncover who ordered the murder, he finds himself at the center of a power struggle between Joowoon and the rival Bongsan organization. Betrayals, secret alliances, and family ambitions quickly cloud the trail. As Gi-jun works his way up the chain of command, his investigation turns into a relentless quest for revenge.

In the slums of Seoul, where everyone looks out for themselves and violence reigns, Gi-jun seeks neither justice nor forgiveness: only the truth, whatever the cost.
