Fighting for their lives aboard the hijacked submarine, ship superintendent Amy Russell and Commander Darius McCann have only one hope for survival. With the lives of millions at stake, they must play a dangerous game of cat and mouse, where capture would mean certain death.
On land, Lieutenant Colonel Sarah Connelly and Commander Bruce Dunn are working to learn the details of the hijacking in time to stop the attack. As mass hysteria paralyzes New York City, the two investigators uncover a trail of secrets as dangerous as the silent weapon aimed at the heart of America.
