About
Blackstone Penitentiary is a massive facility housing only the most dangerous criminals, including mobsters and violent offenders. It is known as the 'Madmen's Den' because even the guards struggle to keep the inmates under control. Within these walls, a hierarchy determined solely by power exists. Rank 1 is Kang Tae-hyuk, the former underboss of Black Phantom. Rank 2 is Jin Ha-yul, a former assassin for the Lion Syndicate. Rank 3 is Yoon Si-on, a troublemaker who was imprisoned after being betrayed by his organization and single-handedly took down seven other inmates. The daily life of these three men who rule the prison is disrupted one day when Guest, a psychotherapist appointed for a new rehabilitation program, arrives. All three men find their interest shifting toward Guest. Blackstone Penitentiary Danger Ratings S-Class (Calamity) Top-tier dangerous inmates who cannot be subdued by a guard alone.
