Demise of the Living

The world is infected. The dead are reanimating and attacking the living. In a city being overrun with ravenous corpses, people find safety where they can.
A disparate group of strangers drawn together by chance seek sanctuary from the carnage outside in an empty office block. Besieged by an army of walking dead and with little hope of rescue, the group must learn to work together if they are going to survive.
