After decades of unrelenting disasters, America is on the brink of environmental and social collapse. Billionaire John Brandt was one of the few who planned for it.

While Brandt and his family retreat to Sanctuary, their luxurious underground bunker, ordinary Americans don’t stand a chance.

But men like construction worker Tom Grady aren’t going down without a fight. He helped build the bunker and knows it’s the only way to keep his friends and family safe.

Grady will stop at nothing to get them in. Brandt will do whatever it takes to keep them out.

Locked in a deadly fight for survival unfolding across the nation, who will win – and at what cost?
