In a daring, brutal act of terrorism, an explosion rocks and topples the Statue of Liberty. Special Agent Michael Walker of the National Park Service is sent to New York as the agent-in-charge. Gina Delgado of the FBI has been placed in charge of the investigation as the lead of the Joint Terrorism Task Force, and 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 the survivors 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.
