Film idea

The name of the film is Locked Out.
A horror film about a group of girls staying over at a mates house, where unexpected visitors call. 


Girl home alone because parents have gone out and invites friends over. Clearly shows its a big and creepy old house and girl is getting ready but with headphones in, the audience then hears creeks and movement form the floorboards above but girl hasn't because she is distracted by the music. The girl then looks over and sees a shadow down the hall, the tension is then brought up when the girl pulls out her headphones and all goes silent, the girl then goes and looks at what the shadow was, but when she does she only sees the cat going round the corner of the door at the end of the hall way.
The atmosphere is then dropped when the door bell goes and her friends have arrived. 
There are now Four girls all in the house they notice lights on out side so two of them go out and turn them off but then try to get back in, but the doors been locked and all we hear is the lock go on the door, (thinking its a joke) one of the girls outside tries to ring one of the girls inside to get them to come unlock the door but there is no signal since there in the middle of no where.  They ring the house phone -after finally getting signal- to see if someone will answer but on the other end is a noise of someone breathing. They then drop the phone and bang on the door shouting the girl's names. They run round the house looking through the kitchen window as they do the see a dark figure slowly coming toward them, the girls look closer because the window is misty as they do the figure has gone and then they feel someone grabs them from behind. The rest of the film is based on the girls fighting for there lives trying to save each other form the weird pschopath.
