The 9/11 attacks were so much more than a bolt from the blue on a crisp September morning. They were more than a decade in the making. Our story starts in a Midtown Manhattan hotel ballroom in 1990. Shots ring out and the extremist rabbi, Meir Kahane, lies mortally wounded. His assassin, El-Sayyid Nosair, is connected to members of a Brooklyn mosque who are training to fight with Islamic freedom fighters in Afghanistan. NYPD Detective Louis Napoli and FBI Special Agent John Anticev catch the case, and start unraveling a conspiracy that is taking place in plain sight by blending into the tumult of the city. It is animated by an emerging ideology: violent jihad.
