It's been four years since the Zombie Apocalypse destroyed human civilization. Billions of people were either killed or turned into one of the blood-thirsty monsters doomed to plague the earth, killing any human left alive. 

A band of misfits attempts to survive together at the end of the world, forming new friendships and family ties in a compound built by their leader years before the fall. But the sudden arrival of a strange new survivor threatens to upend all of their progress. 

He's an amnesiac they found in the woods, covered in blood and wearing nothing but a few scraps of clothing with the name tag 'Dan' as the only clue to his identity. There's something off about him, and the longer he stays around, the more it seems that he's not entirely human. 

When he walks away without a scratch from a freak accident that should have killed him, fears rise among the colonists now that it seems Dan is immortal. No one knows what to make of his mysterious past or his unusual powers.  

But Dan discovers early on that he's not the only one with unnatural talents. Their leader, Jonathan, has been keeping a secret for over twenty years-he knew that the Apocalypse was coming. And now, he's seen something else on the horizon, and he doesn't know if he'll be ready for it in time.  

The colonists are forced to make a choice: stay hidden away behind the walls of their Colony for the rest of their lives or go out and fight to take back their world. Strange developments come out in the case of Dan's identity, the truth about the zombie virus comes to light, and nothing will ever be the same again.
