When Steven Glass's third grade teacher asked his class what they wanted to be when they grew up, Steven's classmates shouted the usual answers: "A fireman!" "A teacher!" "The President!" When his turn came, Steven said, "When I grow up I'm going to be the last man on Earth."

Warning signs don't come much clearer than that.

Nearly thirty years later, Steven Glass is a billionaire. Surrounded by groupies, yes-men, investment opportunities and glamour, all Steven really wants is to be alone.

Really, really alone.

In secret, Steven builds a personal sanctuary nearly a mile underground. He vanishes from public life, goes off the grid. He's finally alone. Well, except for an artificial intelligence companion named after the only girl he ever loved.

There, Steven plays video games, heckles the news, and waits for the apocalypse. When the end doesn't come soon enough, Steven goes to work. He still has billions of dollars to spend - and there must be something he can do to accelerate the coming storm.

Wrestling with his own destiny, unaware of the young stowaways who have discovered his underground paradise, and battling his duplicitous A.I. companion at every turn, Steven Glass struggles to create the reality he has always hoped for - at the expense of the future of every single living human being on Earth...

Unless a pair of eleven-year-old children can stop him and save the world, that is.
