International borders slammed shut. Communications wrecked.

GPS signals nonexistent. Worldwide power blackouts.

The planet balances on the edge of chaos.

Chechen separatists destroyed thousands of satellites in orbit, the effects crippling the world's militaries. Power and communications failures sweep the planet while emergency services are hobbled as fires and powerful storms rip across America.

Still recovering from his injuries, Mike Mitchell returns to his family at Senator Seymour's residence in Virginia, the place a fortress secured by dozens of Secret Service agents. The CIA has tracked down the terrorists that launched the attacks and offers a front-row seat to watch events unfold as a SEAL team closes in - but the video feed goes dead.

Outside the senator's house, thudding detonations as an attack begins.

Scrambling to stay alive, Mike realizes the onslaught isn't only against the Seymour residence in Virginia, but that a furious blitz has begun all over the country. As the full weight of America's military presses on stopping these terrorists, how are the attacks possible? Is it an invasion? Or something more sinister?

With their lives and the fate of the nation hanging in the balance, the bigger question becomes - who is the real enemy?
