Sometimes God gives you a job to do.
And when that happens, you have to drop everything
and just start walking.
Hey, Casey!
How's your sister doing?
She just got her cast off last week.
She's a lot of fun.
Father, that was a lovely service.
You want to talk sometime, the door is always open.
God, is everyone in this family allergic to light?
What do you want?
Just caught mom crying, so that wasn't weird.
You're so mean to her.
She only climbs up on her cross when she wants some attention.
My daughter, Catherine.
She's back from college.
She's different.
Cat?
The way she talks, the way she looks at me.
It's not depression.
I know depression.
There are things going on in the house-- in my house.
There are voices inside the walls.
[voices whispering]
Mom?
I am not a crazy person.
I'm not saying you're crazy--
There is something inside my house.
It's a demon.
A demon?
It's trying to take my daughter.
[window crashing]
Oh, God!
Oh my god.
Father Marcus, what can you tell
me about demonic possession?
I had a dream, and you were in it.
Go on.
There was a child tied to a bed.
Marcus!
You didn't come here for advice.
You came for help.
Who is it?
A girl in my parish.
Maybe.
Now you believe.
-You're afraid? -Yeah.
You should be, too.
You're being manipulated by forces you
can't even begin to understand.
Anybody up there?
[moan]
[loud crash]
[moan]
[loud crash]
I want you to help me.
I won't abandon you.
