Inside a ramshackle old house, a doctor or scientist, who also may or may not be mad, creates a virus that causes the dead to rise and consume the living. For some reason, said ramshackle old house remains intact even after zombies overrun the world, as do the notes of the mad doctor and/or scientist; some time after creating the aforementioned virus, a “crack” group of “specialists” known as the Zombie Squad arrive at the house to find the notes in order to rid the world of zombies, once and for all.
