Narrative idea!

The teaser trailer we are going to make will keep a vague narrative to keep the audience engaged.
It will show two friends going into the woods, they receive a text saying 'party in the woods' from an unknown number and are lured into a false sense of security.
They enter Gundymoor Woods in a cheerful mood and wanting to find the party. It falls dark very quickly and they can't find a party and decide to split up. A scream is heard from one of the girls and the race is on to get them back together. It becomes clear that there is no party. A unknown man is in the woods and hopes to kill one of the girls. A series of clues will be left throughout the woods and one of the girls find this. This includes a mobile phone ringing which is covered in blood, with the name of one of the girls name popping up as they try to communicate with each other, yet this being impossible.
The stalker will appear in the background to create suspense throughout the trailer. One of the girls will be seen being dragged away, yet it will be unclear as to whether she is alive or dead.
The last shot will be one of the girls on their own screaming due to being alone and then blackout to the titles.
