Bear with me guys I've seen this movie when I was so young and got fascinated by it, My recollections might not be as accurate. thanks.
A girl lives in a trashy trailer park, she hates everyone there including her mom, was about to meet her boyfriend but then finds out he got killed, she then saw a couple of demons? they negotiated to sell her soul
She goes back to trailer park to leak a gasoline and lights a cigarette that results to everyone dying except her
She then began to be with the guys who she negotiated with and became accomplces in killing people
Meanwhile a group of teenagers with a pastor got stranded and saw the girl's house, the girl was very welcoming. She had an eye for the pastor and asked him to meet her in her bedroom.
The pastor was conflicted but decided to knock on her door, the girl pulled the pastor to the bed and killed him with a very sharp thread that severed his head and then the head fell off.
Oh and when she messes up her face she replaces it with some sort of plastic? and she pumps her boobs with air
That's all I can remember, I hope someone can help me. I'm so intrigued by this movie.
