An ex-cop and his family are the target of an evil force that is using mirrors as a gateway into their home.

[first lines]
Gary Lewis: [after opening window and seeing that it doesn't lead anywhere] Oh fuck!
Ben Carson: [muttering to himself while in the Mayflower store] Fuck this place.
Ben Carson: They're everywhere.
Angela Carson: What are you talking about?
Ben Carson: The fucking mirrors! They are everywhere. In the department store, on the corner of every street, in the window of every building in the city. I feel... I feel like I'm not the one looking into the mirrors, but they're looking back at me.
Angela Carson: There's no one looking back at you through the mirrors. You're obviously... you're still conflicted about what happened. Maybe you need to talk to someone... professional. Someone...
[Angela sees that Ben doesn't believe her]
Angela Carson: Mirrors are just glass and silver, Ben. That's it. There's nothing behind them.
[repeated line]
Ben Carson: Damn it!
Michael Carson: Don't be scared, mommy. He just wants to come play with us.
Gary Lewis: [to mirror] I wasn't trying to escape.
[mirror starts to crack]
Gary Lewis: [crying] No! Please, don't! Don't! I don't want to die!
Ben Carson: You polish them?
Lorenzo Sapelli: I'm sorry?
Ben Carson: The mirrors. They're so clean.
Lorenzo Sapelli: Oh, no, that's Gary. Gary Lewis. The fella who's been working here before you. He was completely obsessed with these damn mirrors. Spent the entire night cleaning them.
Ben Carson: You gotta be careful of the water, it creates reflections!
Ben Carson: [screaming at mirror] What do you want from me?
Dr. Morris: When one starts to perceive one's own reflection as a completely separate being, one is suddenly confronted with two entirely separate egos, two entirely separate worlds that can strip us at any given moment. Feeling of self-hatred, usually triggered by a psychological shock, can split the personality in two, hence creating two or more personalities with distinct memories with distinct behavior patterns within the same individual. The patient then has the false perception of the existence of two distinct worlds. The real world, and the world inside a mirror.
Ben Carson: [showing Amy picture] Look at the piece of mirror Gary Lewis is holding. Look at it up here, in it's reflective image in the other mirror. It's full of blood. In reality, it's perfectly clean. Not a single drop on it. Not a single drop on it!
Amy Carson: So what? It's probably the angle from which the photograph was taken. What are you trying to prove?
Ben Carson: What if the mirrors are showing us something that's not really happening?
Amy Carson: What are you talking about?
Ben Carson: Just listen to me. What if the mirrors are reflecting something that's beyond our reality? What if the mirrors can actually make us do things that we don't want to do, like making Gary Lewis slit his own throat?
Amy Carson: Ben, listen to yourself. You can't talk like that around here. Don't you want to be reinstated?
Ben Carson: Amy, I'm seeing things, in the mirrors at work. Bad things, to the point where I can feel what they're showing me.
Ben Carson: I know who did this.
Amy Carson: Well in that case, you've gotta tell Larry everything.
Ben Carson: He'll never believe me. Neither will you.
Lorenzo Sapelli: It has been five years since the fire. They're still in a legal battle with the insurance company. Even cleaning up this mess is impossible. I wouldn't give faith about reopening. Besides, who'd ever want to shop here after everything that's happened? You know, the Meredith family acquired this building after St. Matthew's closed in 1952. It was the very first Mayflower to open on the east coast. The company wants up to patrol every couple of hours, but I do my rounds every three. That's more than enough. Anyway, you'll see. Not too much going on. It's pretty calm around here.
Lorenzo Sapelli: [to Ben] Thank god you didn't show up any later. This place gives me the creeps at night.
Ben Carson: I haven't had a drink. I've got a new job to hold me over until I'm reinstated. I'm doing everything I can to get back on my feet again.
[Ben sees that Amy's in disbelief]
Ben Carson: What? You don't think people can change?
Amy Carson: We're not talking about people. We're talking about *you*.
Ben Carson: Amy, I killed a man. You don't just get over that. I needed time. I needed you.
Amy Carson: I was right here.
Ben Carson: Yeah, judging me like everbody else.
Amy Carson: How dare you say that to me! I was the only one at the precinct who defended you. How can you say that to me? I've always been in your corner. I've been the only one who believed in you. You're fucking unbelievable!
Ben Carson: Please, I didn't come here to fight. Look, I'm sorry that I came over without calling. I just wanted to see them.
Amy Carson: We have to set up some rules.
[Ben angrily slams his hand on the wall]
Ben Carson: [yelling] What fucking rules? Come on, Amy! Just tell me what rules I need to follow so that I can see my son on his birthday!
Ben Carson: [to Robert Esseker] Don't make me threaten you!
Ben Carson: [while holding Anna Esseker at gunpoint] My family's not dying tonight.
Anna Esseker: The mirrors are merely windows on our world. It is not the wish of the mirrors to find me, but of what is imprisoned inside them.
Ben Carson: What is imprisoned inside them?
Anna Esseker: At the time that I was at St. Matthew's, Dr. Cane's therapy for personality disorders consisted of locking the patient up in a mirrored room for several days on end, forcing them to confront their own image. Dr. Cane was wrong about his theory. There is no cure for schizophrenia, Mr. Carson. It was something else, and whatever it was, it left me and entered the mirrors. Since that day, it has been collecting the souls of the people it kills. I'm sorry, but if I agree to go with you and return back to that place, I will make it possible for the demon to cross the threshold back into the real world.
Ben Carson: Do you understand what that means for my family? You can't do this. You need to come back with me.
Anna Esseker: I'm going to pray for you, and your family. That's all I can do right now, Mr. Carson. I'm sorry. God bless you.
