Initial Ideas: Childrens Playground...

Autumn time: Childrens playground in daytime -- observational shot of children playing in park, merge shot out into a second shot, same angle of playground, however, its later on the day (initally was around midday now around 6). Girl sitting alone on swing, slowly going back and fourth.

Diegetic sound of her singing a nursery rhyme under breathe, rusty swing creaking as she goes back and forth. Leaves blowing in the wind.

Different angles of her, one of her feet as they touch the ground to push her back and forth. Close-ups of the hinges as they creak.

Cuts here, camera follows feet of a man along the floor, through the leaves. Walking down an alleyway towards the park. Strong sturdy shoes (Doc Martin Boots), dark trousers, diegetic sound of his breathing. Important through the whole film that the audience do not see the man's face.

Cuts to a hand held shot from the man's perspective as he walks towards the playground, jolty, still sound of his breathing.

Cuts back to girl on swing, still singing. Cuts to feet of man once again, extreme close-up shot as his foot lands on a stick which breaks. Edit sound to echoe again and again -- cut back to the girl on swing who stops in her tracks and quickly swerves to look round to see where the noise came from.

Cuts to hand held shot from man's perspective once again, this time he is back against the edge of the alley, breathing heavily out of sight.

Girl carries on swinging, back to the man, we see his silhovette come into shot in the far distance, shot cuts to mid shot from behind the girls head, zooms in and as this happens she turns round. Shot cuts back to her from in front swinging, however, the man has vanished.

Shot of leaves blowing in the wind, then cuts to a close-up of the metal of the slide, suddenly a dark reflection swerves past. Cuts to sand pit where there are large footprints marked across.

Next shot starts as an extreme angle of the girl on the swing from the front. It zooms in extremely quickly until it reaches an extreme close-up of her eyes, she screams, cuts to blackness.

Final shot is of an empty swing creaking back and forth with no one in sight.

Sound: We could use a non-diegetic nursery rhythm being sang by maybe more than one child as a continuine throughout the film. This would juxtapose the thriller genre and the events taking place, to also represent childhood innocence.

Costume: Girl would be wearing something simple and neutral. Something which tells the audience she is just a regular child playing in the park, maybe a bit dirty, hair in a simple pony-tail.
Man--all blacks, maybe a big coat, but we never see him exactly, when he is seen in the background, ensure it is blurred.
