Day One: A series of terrorist attacks spread a cloud of noxious gas over highly populated areas.

Day Two: Higher brain function erodes in those exposed to the gas. Their bodies begin to distort, faces distending, skin sallowing, teeth elongating.

Day Three: The infected disappear into the shadows, fleeing the harsh daylight which has begun to sear their flesh.

Day Four: The world is DEVOURED.

Life isn't kind to Lance York. A full-time job has eluded him for years, his wife loathes the sight of him, his bank accounts are empty, and his wealthy father-in-law revels in his failures.

After he lunges in front of a car to save a sick and disoriented woman, Lance awakens in a quarantined hospital. A devastating plague is spreading worldwide, driving those infected with it insane. Their bodies begin to mutate into horrors that have haunted mankind's nightmares for centuries.

The world descends into chaos as death holds sway in the streets.

With the help of an unlikely ally, Lance must navigate through the collapsing city of Pittsburgh, striving to escape the madness of the Apocalypse that unfolds around them.
