In 1988, young sisters Katie and Kristi befriend an invisible entity who resides in their home.

Randy Rosen: [arguing about the demon] This isn't... Casper the fucking friendly ghost you're chasing man!
Randy Rosen: She got blown in the face!
[last lines]
Kristi: Come on Toby.
Grandma Lois: Let's get ready.
[first lines]
Daniel: [documenting behind the camera] You'll be spending a lot of time in here. This is gonna be your room. There's some kind of animal being de-liced or something. Compression chamber, that's your crib. It's hermetically sealed. And this is your paint color. What color is that, hon?
Adult Kristi: Jamaica bay blue.
Dennis: [from trailer] There's something in the house... Kristi's like connected; it's a real life poltergeist. Kristi's like Carol-Anne!
Dennis: I just gotta film this stuff, I could set my cameras around the house right? I could maybe capture something...
Randy Rosen: Yeah?
Katie: [playing the Bloody Mary game, Katie first explains it] So, you say Bloody Mary three times.
Randy Rosen: Mmm-hmm.
Katie: And then you wait a little bit and then you turn the lights back on; and then you're supposed to see her body in the mirror and she's gonna try to kill you.
Randy Rosen: Try and kill you. Good game.
[chuckles]
Katie: Yep.
Randy Rosen: I don't know why you wanna play this- One of us is gonna be dead by the end of it. I guess it's a one-time game. Okay, let's do it.
Katie, Randy Rosen: Bloody Mary, Bloody Mary, Bloody Mary.
Katie: [Randy turns on the light as nothing happens] Randy!
Randy Rosen: Nothing happened.
[chuckles]
Katie: You turned the light on too soon!
Randy Rosen: Oh, come on, Katie. This is stupid.
[as he walks to the door]
Katie: No, no, no, no, no, no, no! You can't leave!
[blocking the door]
Randy Rosen: Let's just go play doll house or something.
Katie: No, you didn't do it right.
Randy Rosen: What did I not do right?
Katie: You need to keep the light off longer.
Randy Rosen: Okay. Okay. All right. You wanna play Bloody Mary? Let's play Bloody Mary.
Katie: Okay, ready?
Randy Rosen: You're not gonna see anybody play Bloody Mary like I'm about to play Bloody Mary.
Dennis: [talking about what the title to Back to the Future should've been called] It should either be called Back to the Past...
Randy Rosen: No, no.
Dennis: End of story.
Randy Rosen: That doesn't make any sense. It makes total sense.
Dennis: Let's Get Back to the Present, maybe. But, Back to the Past...
Randy Rosen: Back to the Present.
