Ransom Doniphon is a Park Ranger working in New Hampshire's White Mountains National Forest. While on a helicopter search-and-rescue mission he spies a makeshift shelter deep within the woods. When Ransom and his partner investigate there is a shootout leaving three men dead. What at first appears to be a mobile drug lab hidden in the woods turns out to be a homegrown terrorist cell with roots that run deep into state and federal government.

In the year 2077, the United States has become a post-apocalyptic footnote in the world history books. The only place freedom still exists is in a shielded underwater city called The Atoll, where a group of Christian refugees are trying to start over. The Atoll inhabitants are hated for their freedoms and hunted for their technology, but even in their protective bubble, treachery still finds a way in.
