Short, sharp cuts begin, which show the parents worry and distress about their daughters different moods; as this is happening we hear the non diegetic sound of a fork tapping a plate as if it were a ticking clock, which may suggest something is going to happen in time. The fork sound then becomes diegetic and the clips become much faster, building pace and alternating between her plate of food and her fathers face. This builds up to the the climax of her fathers hand hitting the table and Emily attacking her father somewhat out of the blue. Many short clips are put together to show the fast pace of the attack happening. When the next scene cuts, it is of a typical dark night which is present in most horror film trailers making the scene seem dark and dull. As the man's non diegetic sound of 'demon' is said, Emily pushes glass onto the floor in front of her Mother which shocks the audience, with the sound also coming to an abrupt end. It cuts back to a close up shot of Emily's face looking scared and upset which is juxtaposed with the voice of the Jew 'the spirit is the taker of children' at the same time, suggesting she is not the pure, innocence child she once was. We then see a long shot of Emily in the middle of a dark road wearing a typical white nightie denoting her purity and innocence which again is the opposite with her new found self. As scenes then cut and words come up on to the screen we hear non diegetic type ghost voices which could denote the voices in Emily's head which have made her become possessed. Tension is built when all sound is stopped and all we can hear is the Fathers voice reading out of a bible, making the audience wait for the next action from Emily.
There are then short sharp cuts of the 'possessed' Emily accompanied by a hymn type sound, suggesting she has been possessed by something god-like. The sound then comes to a crescendo when the clip repetitively flashes and the box becomes the centre of frame showing the storyline is based around this mysterious box.When the scene cuts to Emily in the bathroom we can hear the non diegetic sound of her Mother 'I saw something in her', then the trailer ends confirming her mother's suspicion with a close up shot of two fingers coming up from her throat, denoting that 'something' is actually inside of her.
