Here’s how the IMDb entry describes what happens next:
Professor Price says, Rest your fingers on the stone lightly, like this. She places the tips of her fingers on the stone. Megan and George do the same. The professor says, Good. Now, clear your minds.
Megan asks, How are we supposed to do that? Have you seen where we are?
Just do the best you can, Professor Price says. You can close your eyes, if it helps.
Megan shakes her head no, but George shuts his eyes. He says, All right, what next?
The professor closes her eyes. She asks, Is anyone there?
Nothing happens.
Professor Price says, Is anyone there?
Slowly, the stone scrapes across the floor. Megan screams, but keeps her fingers on it. George says, What the hell? The professor says, Easy. Stay calm. Keep your hands on the planchette.
Megan says, The what?
George says, The stone.
Right, Professor Price says, the stone. Her eyes are open. The stone settles on YES. The professor nods. She asks, Who is there?
The stone slides from YES to the letter A beneath it. Then to G, back to A, to T, to H, and back to A. Professor Price says, Agatha.
Kristi’s voice says, Holy shit. Ben Rios crosses himself.
The professor asks, What happened to you, Agatha?
The stone spells out T-R-A-P-P-E-D.
Professor Price says, Trapped? You were trapped here, in the mine?
The stone moves to YES.
The professor asks, Why?
The stone spells B-A-D.
Professor Price says, You were bad.
The stone spells B-A-D.
The professor frowns. She asks, How were you bad?
The stone does not move.
Professor Price says, How were you bad, Agatha?
The stone spells out B-L-O-O-D.
The professor says, I don’t understand. How were you bad, Agatha?
George says, Seems pretty obvious to me. She was doing something with blood. Ben says, Maybe she was drinking it.
The stone slides to YES.
Professor Price says, Please, let me do the talking. What were you doing with blood, Agatha?
The stone moves to NO.
The professor says, All right. Who trapped you here, in the mine? The stone spells K-L-E-R-O-S.
Megan asks, Who is Kleros? George shakes his head. Professor Price says nothing. Ben says, I think it’s Greek. Carmen asks, Greek? Ben says, yeah. It’s like the root of clergy.
The professor asks, Where are you from, Agatha?
The stone moves to NO.
Professor Price repeats the question.
The stone does not move.
The professor exhales. She asks, Can we help you, Agatha?
The stone does not move.
Professor Price waits for an answer. None comes. She asks, Are you still there, Agatha? The stone does not move.
Megan asks, What happened? George says, We lost her. He sits back, lifting his hands from the stone. Megan does the same. The professor maintains contact for a few seconds more, then she sits back, too.
Kristi says, What the fuck was that? Carmen says, Yeah, Isabelle, what’s going on?
Isabelle Price starts to speak, but her answer is interrupted by George shouting, Shit! and scrambling backward. Megan screams and stumbles to her feet. The professor raises her hands, startled.
The planchette stone is bleeding. All over its surface, drops of blood appear, swell, and collapse into streams that trickle to the edges of the stone and spill onto the floor. Kristi shouts, Fuck! Megan turns and collides with Ben. Blood pools around the planchette stone. Professor Price stares at it. Carmen says, Isabelle, what the fuck is happening? Blood spreads over the words and letters of the Ouija board. Ben mumbles something. George is praying, Our Father, Who art in Heaven. Blood flows to the edges of the trench in the center of the cave and slides into it. Kristi says, What is this? What is this? What are we seeing? What? Carmen tells everyone to move away from the blood, to come over beside her. The crew does, except for the professor. Carmen says, Isabelle. Come here, Isabelle.
Professor Price turns around. Her face is blank. Her left eye is red, blood pouring from it down her cheek.
The third and final scene is, of course, the movie’s climax. By now, the movie’s title has been realized, as the film crew has emerged from the cave to discover that their panicked flight has carried them off Isabelle’s map. Despite following several seemingly familiar paths, they have remained lost. Their complaints have grown more hysterical.
In the meantime, Carmen has succeeded in coaxing Isabelle out of the trance-like state into which she fell. The sclera of her left eye is still stained red with hemorrhages, but it’s no longer actively bleeding. Prompted by Carmen and Kristi, she has revealed some of the secrets we’ve suspected her of harboring. Her research on Agatha Merryweather, she says, led her to a website that’s kind of a clearing house of weird information. There was an entry for the Bound Woman of the Mine that sounded as if it might connect to the information she’d already gathered. The site kept crashing her computer, so she wasn’t able to read all of the listing, but the portion she finished was intriguing. It concerned a fourteen year old girl who had been responsible for a series of terrible murders in northwestern New Jersey during the early nineteen sixties. This was farm country, near the Pennsylvania line. For some reason, after her apprehension by the sheriff, the local Catholic priest was brought in to consult on the case. This led to another pair of priests being summoned, an older man and a younger one, whose accents no one recognized. They said they were members of a small order, the Perilaimio. Eventually, the girl was released into their custody on the condition she remain confined to her house. At some point thereafter, she, her parents, and the priests were discovered to have fled for an unknown destination. There was talk of a search for her, but it came to nothing.
When Kristi asks what any of this has to do with anything, Isabelle reveals that the website gave a name for the girclass="underline" Agatha Merryweather. Obviously, with the assistance of the Church, she and her family fled east, where they were resettled in Weehawken. The question was, why?
This Agatha was possessed, George says. That’s where the story is heading, isn’t it?
That is what she thought, Isabelle says, until she looked into the order to which the priests belonged, the Perilaimio. It’s an old, old group, maybe older than the Church itself.
What is she talking about? Megan wants to know. How can there be a part of the Church that came before it?
Like Christmas trees, Ben says, or Yule logs. Pagan things the Church folded into it.
That’s it exactly, Isabelle says. The Perilaimio were charged with managing the Keres.
Which means what? Kristi asks.
Death-spirits, Ben says.
Death-spirits? Megan says. How does he know this stuff?
