In a small Ohio town, Halloween night serves as the backdrop for a series of interconnected tales that explore the dark and twisted side of the holiday. In one tale, a high school principal with a secret life as a serial killer contends with the implications of his actions. His story intersects with the misadventures of a group of prank-playing kids who discover a local urban legend about a school bus massacre to be perilously true. As these children delve into the past, their present becomes a fight for survival.

Elsewhere, a young woman's search for the perfect Halloween party leads to an encounter with a mysterious stranger, setting the stage for a revelation that is both shocking and deadly. In another part of town, a cantankerous old man faces off with a mischievous trick-or-treater who embodies the true spirit of the holiday - a pint-sized enigma determined to enforce the rules of Halloween. As the night unfolds, the boundaries between Halloween fun and frightening reality begin to blur, leaving the townspeople entangled in a web of horror and macabre morality tales.
