1) Michelle and Andrew are running from zombies through a school corridor littered with rubbish and signs pointing to an emergency assembly point, with some blood splatter. 2) Michelle gets her hair grabbed by a bloody hand of an undead as they try to go through the door to safety, and she gets bitten on the arm while Andrew tries to free her. 3) They seal the door with chains as more undead arrive. Andrew expresses regret that he couldn't protect Michelle from getting bitten and infected but doesn't want to leave her alone.
