Oralee invents a fictional classmate named Ike and presents a sketchbook as a recovered grimoire to give the ritual credibility and ease Nathan's fears. She designs it as a way to help her brother cope with his grief and nightmares over Maxine's death, not expecting the ritual to actually summon real demonic forces.

Foreshadowing: The fake grimoire becomes disturbingly real when the rituals actually work, suggesting the children have tapped into genuine supernatural power.

The film presents the rituals as genuinely summoning infernal presences. What begins as a harmless childhood game conjures real demons, a rotting corpse from a previous suicide, and mythological figures like Charon. The boundary between magic and reality collapses, turning their attempt to rescue Maxine's soul into a actual descent into supernatural danger.

After Nathan escapes and frees a dog from a bear trap, the film shows a "The End" title card but then continues. Oralee runs through the woods pursued by demons and violent hallucinations. She returns to the campsite, hides in a tent, and points a gun at the entrance. When Nathan approaches, panic overtakes her and the screen cuts to black, leaving her fate deliberately ambiguous and unresolved.

Scholars in the documentary identify a recurring rune throughout the film as being associated with the demon Astaroth. The symbol appears subliminally spliced into the 35mm reel, and historians connect Astaroth to real historical tragedies. This demonic rune serves as the film's central supernatural signature, suggesting the entire cursed film is connected to this ancient entity.

The cannibals cook people alive inside an iron statue of Baphomet, a goat-headed demon figure associated with Satanic worship. This connects to the film's central theme of Hell and damnation, reinforcing that the children have entered a truly infernal location known as "The Antrum", where the devil supposedly landed after being expelled from Heaven.

During their first night in the forest, Nathan witnesses a boat carrying a nude woman being rowed by a figure resembling Charon, the mythological ferryman of the River Styx. He also hears a rattling chain he interprets as Cerberus, the three-headed guardian of the Underworld. These visions confirm the forest is a gateway to Hell, with the children literally approaching the realm of the dead.

Scientists and archivists analyzing the 35mm reel discover disjointed black-and-white fragments spliced into the film that appear to be actual snuff footage.

After Nathan frees a dog from a bear trap and believes they've rescued Maxine's soul, a "The End" title appears, but the film deliberately resumes. This narrative trick creates false closure before revealing the true cost: Oralee's fate remains uncertain as she succombs to demonic pursuit. The meta-structural twist mirrors the film's theme of cursed content that cannot simply end.

The children travel to "The Antrum," believed to be where the devil landed after expulsion from Heaven. They dig a hole as part of their ritual to reach Hell itself, attempting to locate Maxine's collar, a sign they have rescued her soul from damnation.

Maxine, the children's beloved dog, was recently euthanized before the story begins. This loss drives the entire narrative, as Nathan's grief and guilt over his mother's joke about Maxine going to Hell compels him to undertake the dangerous ritual to rescue her soul. The children's grief becomes the emotional engine of the horror that follows.
