When a toxic chemical spill tears open the ozone above rural Texas, backwoods locals mutate into drooling, slime-choked ghouls with an insatiable appetite for flesh. Environmental science student Arlene and hitchhiker Kevin stumble into the madness as small-town life collapses into a grotesque carnival of green vomit, yellow pus, and blood-soaked carnage. Dubbed dialogue, surreal padding, Americana weirdness, and gallons of inventive practical gore make Ozone unforgettable and stomach-churning.
