Story and how the opening sets it up

The main story of our thriller is the idea of a man stalking a woman and her child, and his obsession with them both. The opening features the woman being caught by the man and being hunted down through the woods. It is set up in the open on a handheld camera. It will look a lot more chilling if the whole product is filmed on handheld camera. It will begin in an open area as it will be a neutral area and can make the audience think about location.
