Theme
September 1988: Young Katie tells Dennis (their mother's boyfriend) "You can't see them, only kids can see them." This thematic statement establishes that innocence perceives truth that adults dismiss, and that skepticism blinds us to real danger.
Worldbuilding
The happy household of Dennis (wedding videographer), Julie (mother), Katie (8), and Kristi (6) in 1988. Dennis and Julie are in love, the girls play normally. Dennis notices a strange dust pattern during an earthquake and begins setting up cameras throughout the house to document anomalies.
Disruption
Dennis reviews footage and sees a clear paranormal event: sheets moving on their own, and the shadowy outline of an invisible figure standing next to Kristi's bed. The supernatural presence is confirmed, transforming this from curious investigation to genuine threat.
Resistance
Dennis becomes obsessed with capturing more footage, setting up an oscillating camera in the living room. Julie dismisses his concerns. Randy (Dennis's colleague) helps review tapes and research. Strange occurrences escalate: objects move, doors slam, Kristi talks to her invisible friend "Toby." The family debates whether this is imagination or real danger.
Act II
ConfrontationFirst Threshold
After violent activity where the chandelier shakes and crashes, Dennis makes the active choice to continue documenting despite Julie's anger. He commits fully to proving the supernatural presence exists, even as it threatens his relationship and family safety. He will not stop the investigation.
Mirror World
Dennis's relationship with Julie and the girls represents the thematic mirror: trust vs. skepticism, protection vs. denial. Julie embodies willful blindness to protect normalcy, while Dennis represents the need to confront uncomfortable truth. Their deteriorating relationship reflects the cost of facing reality.
Premise
The "promise of the premise" - found footage paranormal scares. Escalating nightly hauntings captured on camera: Kristi levitating, invisible Toby playing games, sheets pulled off beds, babysitter terrorized and fleeing. Dennis and Randy conduct "Bloody Mary" ritual. The activity becomes more aggressive and targeted at the family.
Midpoint
False defeat: Dennis discovers all his tapes have been destroyed - someone or something doesn't want the evidence preserved. Simultaneously, a violent attack occurs where Julie is seemingly thrown against a wall. The entity escalates from observer to aggressor. Dennis realizes they're not documenting a ghost - they're being hunted.
Opposition
The family attempts to flee to Julie's mother's house. However, the haunting follows them. Kristi becomes more possessed and compliant with Toby. Strange noises come from the basement. Julie's mother Lois acts strangely protective of Kristi. The supernatural force gains ground, isolating Dennis as Julie turns against him. The girls are increasingly under demonic influence.
Collapse
Dennis discovers Julie's mother Lois is part of a coven, and the entire haunting was orchestrated to claim the girls for a demon. Julie is murdered - her body falls from the attic, breaking her neck. Dennis's surrogate family is destroyed, his protection has failed, and he realizes too late that evil has already won.
Crisis
Dennis, alone and terrified, searches the grandmother's house for the girls. He finds evidence of the coven throughout. He hears chanting from below. He must descend into the witches' lair knowing he cannot win, only hoping to save Katie and Kristi from their predetermined fate.
Act III
ResolutionSecond Threshold
Dennis finds the coven gathered in the basement with the girls. He understands the full horror: this was planned from birth, Julie was complicit or deceived, and the girls are being given to a demon. With no hope of victory, he chooses to fight anyway - attempting to save them despite certain death.
Synthesis
Dennis confronts the coven but is overpowered by supernatural force. His body is violently destroyed off-camera. Young Katie witnesses the horror. The camera falls. The ritual completes - the demon Toby claims the girls. The coven has succeeded. Katie and Kristi are lost to darkness, explaining their fate in the future films.
Transformation

She is transformed from innocent child to vessel of evil - the final image mirrors the opening but shows complete corruption. The girl who could "see them" is now one of them.
