Maggie and Negan venture into the shadowy depths of a severed Manhattan, an island long isolated from the dying world. Within this towering labyrinth of rust and ruin, prowling corpses roam concrete canyons while hardened survivors have carved out a fierce, lawless realm of their own. Together, they must navigate a graveyard of skyscrapers where every alley hides a nightmare and humanity has been wildly remade.
