An explosion rocks and topples the Statue of Liberty. Special Agent Michael Walker of the National Park Service is awakened by his boss and sent to New York as the agent-in-charge. Not long after he lands, he learns two things - that Gina Delgado of the FBI has been placed in charge of the investigation as the lead of the Joint Terrorism Task Force and that threats of a second terrorism attack are already being called into the media. While barred from the meetings of the Joint Task Force for his lack of security clearance, Walker finds a young boy among thesurvivors with a critical piece of information - a video linking the attackers to the assault. As a radical domestic terrorist group threatens further attacks against America's cultural symbols, powerful forces within the government are misleading the investigation to further their own radical agenda.
