Non-linear beginning - starts when friends find out one person is missing. Will be a birds eye view in production. Both show obvious distress.
Fades to actual beginning - friends are meeting up near forest so they can explore. All seem up for it but one feels ill and a bit off (back left)Extreme close up on ill person's significant clothing item.
2 boys feel nervous but one seems more courageous. He encourages them to keep going. Will feature dutch tilt to represent the dis-equilibrium/something's wrong.
They hear noises that are clearly not natural of the forest. Will feature handheld shot/POV which will be shaky to a degree to demonstrate distress. Possibly could include a filter to portray same effect. Courageous one will be keen to explore it but others wont.
Two of them realise one is missing, and find signs of people here before. They intend to backtrack and find way out. ECU of phone with no signal.
Upon backtracking, they find the same significant item that was shown at beginning with an ECU. Both characters stop and fades into credits. Long shot of both characters from behind. Possibly feature glimpse of un-human things thad had taken the friend.
