In-depth Plot summary

here's a write up of all the events that take place during the film so that I don't forget about them, and that everyone else can see how I plan to structure the film in terms of its narrative as opposed to visually;

• Film starts with an establishing shot of a back street in Southwark.
• A Man is walking down the back street, hunched over and clearly in a hurry to get somewhere. In one hand he carries a briefcase full of paper.
• He checks his watch.
• The clock ticks very rapidly, representing his restless attitude.
• He begrudgingly looks back up and continues marching towards work.
• Eventually he gets to a railway bridge and walks under it.
• As he walks under the bridge, something flies around behind his head, causing him to stop and look around.
• It then flies in front of him, fully catching his attention, causing him to follow its movement with his head.
• The camera track-pans out as we see what has caught his attention; it's a huge street painting covering the entire of the wall next to him.
• The man raises an eyebrow at the painting, thinking of it as little more than another piece of 'yobbo grafitti ruining the nation'.
• As he looks at the painting, the Falcon at its focal point starts to move about, startling him and causing him to fall backwards onto the pavement and drop his briefcase, scattering the contents all over the pavement.
• He looks down at the pavement and panics, trying to pick up all of the papers he's just dropped and put them back in his briefcase before they get dirty.
• As he's doing this, the bird circles his head, eventually stopping to land on the brim of his hat.
• The man is unimpressed by the bird and tries to shake it off his head, dropping the papers he'd just picked up.
• The bird flies off and back into the painting.
• The man, angered by the bird, gets up and tries to follow it into the painting.
• He collides with the wall, hitting his head and knocking himself back onto the pavement.
• After pulling himself back up, he rubs his head, then gets distracted by a light source coming from the wall. He looks up and stares at the wall in disbelief.
• The entire painting has now come to life and is now moving as if it were a film.
• He looks around him to check for film projectors, but doesn't see anything that could be used as one.
• His attention then gets caught by the bird again.
• Now thoroughly intrigued by the painting and the fact that the bird seems to want him to look at it, he gets up again, slowly walking towards the painting to examine it more closely.
• As he moves in to look at the painting, the camera suddenly zooms in and tracks the back of the falcon as it flies through the different scenes represented within the painting.
• It flies through a medieval street and up towards the old London Bridge.
• The camera does a swivel pan so that it's facing the side of London Bridge as the bird flies alongside it. One or two birds are doing the same thing in the background.
• The sky begins to turn red as the bird flies alongside the bridge.
• At the end of the bridge, we see that the sky was turning red due to the great fire roaring on the other side of the thames. 
• The fire consumes the bird and the buildings.
• After a few seconds, the bird breaks out of the fire and into the smoky clouds over 18th century London.
• It spots a low-flying pigeon and begins to tail it, flying low into a victorian/ edwardian street as it follows it.
• The pigeon flies into a cloud and the Falcon follows it.
• In the cloud we see what looks like a searchlight.
• As the Falcon flies through the cloud, the scene changes again to the sky over London during a WW2 bombing raid. Searchlights move across the dark background
• We see the pigeon again, though this time a package containing a letter is strapped to its back.
• The falcon attacks the pigeon, catching it out of the sky.
• As it attacks the pigeon, a Spitfire flies into view, trying to shoot down the falcon in order to recover the letter attached to its back.
• The Falcon escapes from the Spitfire and into a cloud of thick smog.
• As it flies through, dead falcons begin to drop out of the sky.
• The background changes to 1960's London, during one of the infamous 'Pea-Soupers' -poisonous smogs common during the 60's in London-
• The smog rising from a nearby factory begins to morph into the shape of a wispy skull.
• The skull lunges out and attempts to eat the Falcon -pollution killing the falcon population-
• The skull's jaws clamp shut around the Falcon.
• The Falcon the breaks out of the Skull, causing it to explode outwards into wisps of smoke.
• It flies towards the Tate Modern, flying into the modern era, showing that despite all the hardships its species has faced, it's still living in London to this day.
• The camera pans out of the painting to show the man, looking at it in awe.
• Eventually, the sounds of the city of London start to fade back in, and the man suddenly realizes how long he's been staring at this painting.
• He looks at his watch to check the time, then looks at the floor, noticing that his papers are still scattered all over the pavement.
• He starts panicking again, this time trying to pick them up even more frantically than before.
• As he puts them back into his bag, he hears mewling coming from the sky above him.
• He looks up to see an actual falcon flying over the city of London
• He then looks back at the painting, feeling unsure about the fact that he's panicking again.
• After one last look at the painting, he calms down, looks at the papers on the floor, then slowly picks them up, puts them in his briefcase and stands up tall and proud, comfortable in the fact that he doesn't have to worry or panic about his life. 
• He walks away from the painting, feeling happy with the experience that he just had.

I feel that there are still aspects I can work into in greater detail during production, but for the most part this is what I plan on doing script-wise for the final film.
