In a small rural town, an elderly witch named Miss Osie raises the demon Pumpkinhead to avenge the death of her deformed and abused ward, Tommy. Years earlier, a group of local teenagers had tragically killed Tommy after discovering his secret hiding spot in the woods. Now, a new generation arrival in the form of Sheriff Braddock and his daughter Jenny sets the stage for further terror when they inadvertently disturb the witch's sacred ground, awakening the bloodthirsty demon who is hell-bent on seeking justice for Tommy's wrongful death.

As Pumpkinhead wreaks havoc on the townspeople, targeting those connected to Tommy's murder and their descendants, chaos ensues, and the terrorized community finds itself scrambling for survival. The sheriff, along with a few town locals, needs to uncover the mysterious connection between the past and present events to put an end to Pumpkinhead's reign of terror. They delve into old legends and lore while battling their own fears and guilt in hopes of stopping the relentless demon before it exacts its final act of vengeance.
