New York City is plagued by a series of terrorist attacks after a prominent Islamic leader is abducted by the US military. To combat the escalating violence, the FBI's Counter-Terrorism Task Force, led by Anthony Hubbard, joins forces with CIA operative Elise Kraft to track down the responsible terrorist cells. As the bombings intensify, the government responds by imposing martial law, deploying US troops, led by Gen. Devereaux, to the streets of New York City.
