Pumpkin is the last girl on Earth and the sole survivor of a humanity-ending plague, scavenging the wasteland for supplies on Halloween's eve. Her solitary holiday ritual is shattered by the arrival of a savage gang of raiders at her doorstep, led by the fearsome Thalia. Outnumbered and armed with candy, wit, and weapons, Pumpkin must unleash a ferocious defense to survive the night.
