While on a visit to the United States, Pope Pius XIII is kidnapped by a terrorist cell calling itself the Soldiers of Islam. If the United States and its allies do not meet their demands, the pope will be executed.
When FBI Specialist Shari Cohen is called to track down the terrorist cell responsible, she learns that she is not alone in her task. Deep inside the Vatican walls, a secret order has dispatched a clandestine op group of elite commandos known as the Vatican Knights. Their mission: bring the pope back alive. As Cohen and the Knights work in tandem, they uncover a White House conspiracy involving high-ranking officials on Capitol Hill.
But when Cohen begins to get too close to the truth about the pope’s kidnapping, she becomes the target of indigenous forces trying to keep the conspiracy safe. But in order to get to her, they must go through the Vatican Knights.
