Basic Plot

Once completing our research and looking over some basic thriller conventions, we came up with a basic outline to our film opening.
Characters
two females - friends (Redhead, Blonde)
one male - unknown identity (Stalk)
Setting
an outdoor scene to begin with... setting un-important, keeps focus on the story.
a dark room scene... reveals the main plot of the film.
Plot
Two girls talking, everyday conversation - focus clearly on red head, blonde appears to be just a random friend. Redhead bumps shoulders with Stalk who appears to be a photographer, taking pictures of the scenes around him. Redhead apologises dismissively, carries on walking, talking to Blonde. Focus then turns to Stalk, who accepts her apology, but clearly continues to watch the two girls as they walk away. It then becomes apparent that Stalk is actually taking pictures of the two girls... specifically Redhead who is still the main focus of the two girls. Scene then flips backwards and forwards between Stalk taking pictures of the girls and him in his dark room developing his pictures. The entire sequence up to this point makes it so that the audience assumes Redhead is the girl Stalk has an obsession with. As one of his pictures finishes developing, Stalk looks at the picture - a shot of the two girls - and then grabs a black marker. We see Stalk scribbling on the picture, unable to see what he is doing. Upon picking up the picture and hanging it to dry, we see that the Stalk has completely scribbled Redhead out of the picture, with Blonde being revealed as the girl he has an obsession with. The camera then moves to unveil a large number of pictures in the dark room, all of Blonde, with the rest of the people in the pictures having been scribbled out.
