Pitch

Story line for opening sequence:

Five seemingly unconnected people are shown, four of which do socially frowned upon activities (the businessman bumps into someone and doesn't apologize, the cyber bully sends mean texts, the stuck up girl throws chewing gum on the ground and the urban teenager looks at a woman in a dirty manner). Every time these bad things happen it cuts to news footage of extreme versions of all these events. These four characters all end up in the same lift, despite not knowing each other, and the fifth character, the opening sequence "antagonist" is rushing to get to the lift. This is all very confusing for viewers as they will be left wondering how they all ended up in the same lift, why was the women rushing to get to the lift, and crucially, why does she kill them in the lift?

Well following on from our opening sequence the rest of the film narrative would show the viewers that this "antagonist" was a psychic and she knew they'd all be in the lift together, and had actually manipulated them into going into the lift previously. She'd killed them because these four people are actually much worse than first perceived (the businessman hits his children, the cyber bully caused someone to commit suicide, the urban teenager has been involved in crime such as rape etc, and the stuck up women has been involved in fraud) and she in a way is an "anti-hero" - she's killed them to rid the world of four bad people. So our opening sequence in a way is a flash forward, leaving questions to be answered as the narrative progresses. 

If a viewer watches our opening sequence again, they'd then realize that the news footage is in fact relevant to the four characters darker backgrounds.
