Original Film Idea - Individual

My Idea It was a Friday afternoon at college and a group of five teens (3 boys and 2 girls) are discussing their plans for the night ahead. They all arrange to meet up at a central point of them all and decide to take a short cut through a field on route to their party destination. They come across a desolate house on the way and some are dared to go in. One girl and one boy refuse but the alpha male and his sidekick force entry into the building followed by the promiscuous female as they make their way inside. The remaining three hear strange noises and see shadows in their surrounding so choose it is a safer idea if they go find their friends inside the building. As soon as they have all entered the building horrific events begin. Eventually they do find the two lads but not as they would have liked. They find them dead by twisted circumstances so instantly plan their escape. Unbeknown to the alive who or what caused this they quickly make their escape. During the mission of escape they meet the killer who also tried to claim these victims. They are shown visions of what this building used to be - an orphanage. They see the dreadful past of how children were tortured by people they trusted. They then come to the realisation that what is haunting them is a tortured soul of one of the children, Violet Whitlock, who is filled with rage and seeks revenge. She is only happy when she inflicts pain and upset on the living. Luckily the remaining two escape into the woods nearby but hear screams from their female friend coming from inside the building. They bravely decide to go back to find that it was a trick and they were lured back by Violet. The two are them parted and the final girl escapes and retrieves help from the police. You are never told what happens to the final male or Violet, in order to leave it on a cliffhanger for sequel opportunity.
