Exploring a cave, Tom finds himself trapped when a series of earthquakes seal the cave entrance. Weeks later, he pulls himself out.

He can't believe his eyes: there's nothing but ashes for miles.

A forest fire?

He sets out to find help, or maybe a phone to call his wife, but there's still nothing but ashes.

When he finds people, he learns a terrible truth: the world as he knows it is over... destroyed.

Tom tries to pull this world towards a new civilized order, but he soon realizes that in a fight for survival he cannot do what he wants. What he discovers instead is something that will horrify and change him forever.
