When an Oregon crew member falls victim to the poison, Juan Cabrillo will stop at nothing to find an antidote before it is too late. He and his team must connect an ancient mystery with a cunning modern enemy in order to save millions of innocent lives, including their own. His search for answers leads to a 2000-year-old Roman mystery and a plan to bring down a nation by a ruthless enemy acting from beyond the grave.
