This was done before our trip to the BFI, so it an out of date synopsis.
The opening scene will start off with Charlie-Ann being interviewed by the police after the death Emma. (This will make sence during the end of the opening scene, when Emma dies.) We then see short clips of the school, the playground, and the corridor. This will give the indication that the school is deserted, and the lights will flicker in the coridor to give a sense of eerieness. It will also be silent, and the lights will be dim. We then see Charlie-Ann and Emma walking into the school to finish off some work that is due in the next day. They then enter the classroom, get there books out, and begin working. You will then see a close up of the clock showing 4 O'clock, and it will slowly fade out and back, and the time will have changed to 6 O'clock. Emma and Charlie-Ann are just finishing there work, when the door suddenly creeks open.
Charlie-Ann then goes up to shut the door. As she is standing by the door, she hears voices, and sees a dark shaddow go past. She goes out the classroom and down the corridor to see what is going on. She gets towards the end of the corrider to see that there is nothing there, and makes her way back up. As she begins to walk back, all the doors in the corrider slam one by one. The lockers begin to shake, and she hears more voices. She goes to one of the doors that slammed to see if anyone is in the room.
As she opens the door, we see a match on action shot of her opening the door and looking in the room. Behind her is a dark figure with a knife covered in blood dripping on the floor. (Charlie-Ann is unaware of this). She sees that nothing is there, so runs back to the classroom to tell Emma. She comes back to the room to find Emma dead, laying on the table covered in blood. Charlie-Ann screams, and the opening scene ends.
