A retired LA counterterrorism cop and a fearless Army doctor risk everything, including their burgeoning romance, as they battle clandestine Iranian operatives bent on the slaughter of thousands of innocents and ultimately the destruction of America. After a yearlong lull, local Iraqi insurgents launch a deadly mortar barrage at the sprawling Camp Victory Base in Baghdad, Iraq. Rick Sutherland, a retired LAPD lieutenant working as an embedded counterterrorism advisor, is wounded in the attack, and a local interpreter is killed. Along with Major Nancy Weaver, his former doctor and now partner, Rick embarks on an off-the-books investigation that quickly morphs into a race to stop murderous Iranian operatives from exploding multiple dirty bombs during a critical meeting of US and foreign heads of state. Working together, Nancy and Rick make a formidable team-but will it be enough?
