He thought he was preventing a Zombie Apocalypse by sending out the zombie mist, when instead he set things in motion to cause it. Those who come in contact with the mist will be turned into zombies. As he is a bit muddled, he needs help to locate the antidote in his lab and release it. We have less than an hour to prevent the Zombie Apocalypse and save the world.
