The story opens in a gritty metropolis where shadows stretch across neon‑lit streets and the line between order and chaos is perpetually blurred. A powerful crime boss, scarred by a recent, brutal betrayal, is driven by a relentless need for retribution. His world is a tightly wound web of loyalty, intimidation, and the ever‑present threat of unseen enemies, all set against a backdrop of pervasive corruption that seeps into every corner of the city’s institutions.

Enter Jung Tae‑Suk, an upright police officer whose dedication to justice is matched only by his frustration with a system that often turns a blind eye to the darkness lurking beneath. His methodical mind and unwavering sense of duty make him a natural investigator, yet he is constantly reminded that the law he upholds is as fragile as the trust he places in his superiors.
