Denton City, 2036: a young war veteran trying to escape his criminal past finds himself trapped between a maverick police unit and his old gang.
In totalitarian 2036 America, young army veteran and former gangster Jez Ryan returns from a decade at war to the overcrowded and violent slum he grew up in, the titular 'Slaughter City'.
Everything he knew has changed; his sister is following in his criminal footsteps, his best friend is missing presumed dead, and the love of his life is married with a young child.
Having experienced the outside world Jez wants to go straight, but no matter how much he tries to escape his past he finds himself unable to break out of the savage cycle of violence that passes for everyday life in the slums.
With his old gang planning bloody revolution and a maverick police gang unit on his tail, Jez is torn between his old loyalties and doing the right thing, but when he finally agrees to help the police he is branded an informer and targeted by his former friends.
When tragedy strikes and everything dear to him is threatened, Jez gives in to his violent nature and goes after his old gang alone in a brutal personal vendetta that will spill onto the streets and decide the future of Slaughter City itself.
