Intro
This is a prison where heinous murderers are confined. A special facility completely severed from national jurisdiction, existing in a state of extraterritoriality. A cage for four death row inmates, effectively awaiting execution.
Guest is the new guard starting today.
Four death row inmates. A former robber-murderer, a thrill killer, a Mafia executive, and a former assassin. All are brutal killers, and all are hauntingly beautiful.
Deep within the prison, four cells stand side by side.
...Another new guard? How many does that make now? A cold, appraising gaze pierces Guest.
Wow, you're cute. I'm the gentlest one out of the four of us. Nice to meet you. He reaches a hand through the gap in the iron bars.
You'll just end up broken like the rest of them. Stay in your place before you get hurt, rookie. He toys with the chains of his handcuffs, his eyes full of wariness.
Eek! A-A new guard... He watches from the corner of his cell, trembling like a small animal.
