Billions are dead and the few that are left start to realize they are not alone. Initially when the dead begin to rise, they are not very threatening. However, in a short period of time, the lurching bodies begin to get their most basic senses back and this makes them much more dangerous. When the dead become attracted to light and sound, the survivors have no option but to live in silent darkness.
