Planning:Final Idea.

The beginning of our thriller will start with a montage shot of random pictures of a couple,and an outsider,along with a range of words like "Love", "Lust" and "Revenge". The aim of this,is for it to not make sense at first.  Then, after a few seconds, the shot will zoom out to reveal a silhouetted figure looking at a wall covered in all the photos and words that were just seen. This room will have very low key lighting,and the only light source will be shining on the board, highlighting it.
The scene will then change to the female victim's house where she is getting ready for the party. Here, her  character will be persued as very happy, sweet and innocent. The audience will grow fond of her,but at the same time, they will already know that something bad is going to happen to her.
Once she is ready, the female will leave her room and turn off the light. There will then be a deep focus on her mobile that she has left on her dresser. The camera will remain on the phone for a few seconds so the audience can read the text message on her phone that will be from her boyfriend advising her not to go to the party.
The next section of the production, we will cut to the boyfriend's house where he is sitting playing a video game with two of his friends.  He will look really worried, as he has just sent his girlfriend the text about not going to the party.  His friends will be comforting him at this point,also.
Then, we will see the female arriving at the party, and there will be a close up of her phone alerting the message again in her bag, and she still doesnt notice it. The audience should start to feel a little more on edge as they know that something bad is going to happen to her.
Once she gets inside the party, there will be a strobe light effect, and we see the female starting to get drunk. The camera movements will be quite shaky here, to highlight this.  Then, the camera will cut between the female, the strobe light, and the silouhette of the antagonist quickly.
After this, the female will leave the party and begin walking home through a park. The only sound that is heard at this point is her foot steps. Then we see someone following her, and then she gets kidnapped.
The scene will then fade to black,and then the female will wake up tied up in an unknown location. At this point the antgonist's identity will be revealed to the audience and female victim. After a series of torture methods, the antagonist will experience a flashback of the female and her boyfriend together.  Then it's clear that the antagonists intentions have changed(he has gone from wanting to torture her, to actually wanting to kill her).
To end the scene, it will be left on a cliffhanger, as the antagonist will be seen grabbing a shovel, and digging a hole in the ground-clearly meant for the female. Then the screen will cut to black and the scene will end.
