In the remote mountain town of Graven Hollow, autumn is more than just a season — it’s a warning. Every thirteen years, as the harvest moon rises and the leaves turn blood-red, the town prepares for a ritual it dares not speak aloud. When a group of college friends arrives for the annual fall festival, they’re drawn into a chilling legend about the Hollow Man — a masked figure born of fire and betrayal, who returns to collect a blood debt. As the friends unravel the town’s secrets and fight to survive, they discover that tradition runs deep… and some roots are soaked in horror.
