Imagine waking up in the future to find you're all alone. All around you, New York City stands shattered and empty, the streets deserted, the buildings in ruins. The end of the world has come and gone and left nothing but you. You have no memory of who you are, no memory of what has happened.

Now imagine you're not alone.

For one man, this nightmare becomes a reality, a world of desolation and dangers beyond his imagining. Haunted by ghosts from his past, hunted by the city's new inhabitants, he strives to survive against the odds, and with the help of an unlikely friend, he keeps his eyes on the horizon, waiting to be rescued.
