First 2 minutes of film

The film begins with Adam running through the woods in daylight. He is frantic and scared. He begins pinpoint details and listening for sounds. He sees a figure and runs faster, tripping over a log and hitting his head in the process. Face down in the mud, Adam begins to hear a groaning sound with twigs snapping. The noises get increasingly louder, he is in and out of consciousness until finally a zombie appears within his line of sight. At this point Adam awakens from a dream, startled, still with the groaning noise in his head, this time more distant with the additional banging. He gets up out of his bed and goes downstairs, shouting for his housemate. But there is no reply. In the background there is an emergency TV broadcast and the banging noise is louder now. He opens the curtain to a bright light and several figures at the window. He finally makes sense of the unusual situation and looks at the TV broadcast. He then hears a coughing from the settee, its his flatmate. Adam asks if he is okay, he replies 'yes' but then coughs up a small amount of blood.
