In an alternate 1966 America, President Kennedy fails to avert the Cuban Missile Crisis in 1962, leading to an unending nuclear winter across the nation. The country’s infrastructure crumbles, its defenses are obliterated, and its citizens endure extreme radiation sickness, transforming them into grotesque, cannibalistic creatures. Tracey Arnold, a man adrift and grappling with his past deeds, roams this desolate landscape, perpetually wrestling with his own humanity and haunted by the relentless presence of the Stray, which won’t allow him to forget.
