In the future, Las Vegas is nearly destroyed. Rebuilt under a dark cloud that blocks all sunlight, Sin City takes on a whole new meaning.
Beneath the neon, The Pagliacci Serial Killers are on the loose and a new drug called "Colors", infused with nanotechnology, is killing thousands. Violence erupts as the mutant population take to the streets to protest working conditions and the disappearance of their loved ones.
Big Tech, the wealthy elite, and corrupt politicians attempt to cover it up. They can't allow anything to interfere with the elections, profits, or their plans.
Can hard-nosed detective Alton Cold and his A.I. car Bessimer catch the killers, stop the cabal, and expose the truth? Or will the appearance of a mysterious woman cloud his judgement as the unnatural cloud darkens the sky?
To save the people he cares about, he'll put everything on the line to confront a darkness far worse than the night.
