Title sequence narrative

The following is a complete outline of the narrative of our opening sequence:

Arran Mason is lying lifeless in a dead-end alley. He’s horribly beaten and obviously unaware of his current location. As we get to see more of him, he narrates what has happened, though he doesn’t give hardly any information to why he is beaten. The only major point he gives away is this: ‘It started thirty days earlier...’

Along with this line, there is an instant flashback to when ‘it’ all began. Arran is at home preparing for a monotonous day of work with the help of his caring wife, though he only reluctantly allows her. Soon, he is making his way through London, just passing Tower Bridge. Arran fails to notice two shady men keeping a close eye on him. As Arran gets closer to his workplace, the men follow tentatively. Whilst he is walking down a mildly-crowded street, Arran suddenly realises the two men’s presence and desperately tries to escape them by running.

Later on in the deadly chase Arran mistakenly runs into a blocked alley and tries to confront his two enemies. Unfortunately, the men are stronger than he expected and is now completely powerless...
