Colonel John Cutler, a tough Special Forces Commander, is appointed as a liaison between the U.S. Army and Congress and reassigned to Washington, D.C. Cutler is tasked with tracking down a secret group of revolutionary businessmen, politicians, and military elites called the Caretakers, who are planning to assassinate the President and overthrow the American government. After losing three agents and failing to identify the forces behind the rebellion, Cutler recruits elite assassin Cruz McCall to counter the rebels' attack. McCall is an intuitive investigator who is not bound by rules or regulations and is a true American warrior. She and her sidekick, Juan Mendoza, previously served under Colonel Cutler as Army Rangers. McCall willingly accepts the assignment, unaware that she is heading into a confrontation with some of the most dangerous and powerful enemies she has ever faced, and one mistake will cost her life.
