Synopsis for new idea for a Horror Movie

A young girl of about 16 and her brother are moving into a new house with their mum and her new husband. The hous is big and old fashioned, and is on the outskirts of town. As they are moving the boxes in, the older brother is winding up his sister, telling her that the house is haunted. She brushes him off, telling him that she never has and never will believe in ghosts.
During the night the teenage girl, Cassie, is having trouble sleeping, listening to the 'bumps in the night', suddenly she sits up, her eyes are open and they flash bright red, they then fade to their normal colour and she slumps back into her bed.
The next morning the family dog barks at the girl for no reason. Over breakfast the mother is talking about what they can put into the loft, the stepdad snaps at them, he tells them that nothing can go up into the loft. They all find this a bit strange but brush it off as stress from the move.
Cassie finds a battered box, thinking it is one they must have missed in the move, goes to put it with the others, but a voice in her head, one whaich is not her own tells her to open it and look at what is inside.
She finds an old family photo out in fromt of the house; it is of the stepdad with his previous family. There are also newspaper clippings showing a picture of the previous teenage daughter who went missing a few years before.
When Cassie reads the clippings she has flashbacks of the previous girl's life in the house. She is running away from an unknown villain, all you can see are the hands of the antagonist trying to grab the girl. She trips and falls to the ground where the hands drag her away.
Cassie goes to her room, where she appears to be sitting on her cabin bed talking to herself, you then here the voice from earlier relpy to her and see the previous daughter sitting at the desk under the bed.
Throughout the next few days Cassie talks to the girl, she finds out that they had the same stepdad, and she has more flashbacks.
She has a premonition of herself in the same scenario of running away from the hands, the hands which have been tormenting her dreams.
The stepdad asks her to help him with the shopping and put some things away for him, she goes with him and he is very strict and protective about her when they are out.
After more dreams and premonitions all including the hands and images of the loft, she figures that to get the answers she has to go into the loft, the previous girl from the visions tells her that is the right thing to do, but to wait until everyone has gone out for the day.
Cassie waits for a day where everyone has gone to work and she has been left home alone. She goes to the landing and gets out the ladder for the loft, half way up the ladder she hears someone come in through the door. Scared she comes down the stairs and tries to act normally in front of the step-dad. She asks him if he would like a drink and goes out to the kitchen to get him one, suspiciously he goes up the stairs and finds the ladder up to the loft.
He comes back down the stairs and slams into the kitchen. He asks harshly if she has been up in the loft, she replies trying to act inconspicuous that she has not been up in the loft, and that she wasn’t planning to either.
He shouts her, telling her that she is a liar, all the while he is advancing on her. Cassie backs away from him running through the house, he follows her trying to grab her, she grabs the cordless phone from the side and tries to dial the police as she runs, but her hands fumble too much to ring properly.
The chase pursues all through the house, until Cassie is back in the kitchen, fumbling the phone in one hand and the lock on the back door with the other, she manages to get out into the garden just in time, and runs towards the back fence and tries to get over the back fence. As she is trying to climb, he catches up with her, pulling at her by the ankles back down to the floor, he drags her, screaming back towards the house.
She is still fumbling the phone in her hand trying to ring the police, he rips it from her hands and chucks it across the room, where is smashes on the wall, falling to pieces on the floor. He drags her kicking and screaming up the stairs towards the loft.
He pushes her into the loft and pushes her across the floor, it’s very dark and dusty, and when her eyes adjust to the light she can see the morbid images of a girl, and she can not work out what is happening to the girl in the pictures as they are too distorted.
He explains to Cassie that the previous girl was just like her, and tells her what he did to her and how he is going to do the same to her, and she is going to be very quiet and not say a word to anyone. She begins to scream and he kicks her, and tells her that he just told her to be quiet.
They both hear the door being unlocked downstairs and Cassie scrambles for the hatch, she tries to scream and he covers her mouth.
Down stairs the mum and the brother hear the struggle and wonder what is going on, they both go to the stop of the stairs as they see the loft hatch being shut and the terror in Cassie’s scream. The mother goes up into the loft and the step-dad pushes her to the floor. The brother tells her to go downstairs and phone the police, as he goes up to the loft.
Down stairs the mum finds the phone smashed on the floor, and fumbles with her bag trying to find her mobile phone.
Mean while upstairs the brother managed to get into the loft, Cassie seeing him, but the step-dad doesn’t. The brother mouths to Cassie not to look surprised, and he picks up the loft hatch and smashes it over the Step-dad’s head knocking him to the floor, the mother has phoned the police and helps Cassie down from the loft.
When the step-dad comes back around the police are there and are arresting him, with all the evidence from the loft they explain to the family about his previous family and what happened.
That night Cassie wakes up in the night, again her eyes flash red and fade back to normal, then you see the previous girl wave and leave the room.
