NYPD Detective Louis Napoli and FBI Special Agent John Anticev fear an attack is coming, but without their mole, Emad Salem, they’re blind to the machinations of the Brooklyn terror cell. Then on February 26, 1993, a bomb goes off in the basement parking garage of the World Trade Center, killing six people and injuring more than a thousand. We follow investigators as they chase down clues and round up suspects, including one who bungles his way directly into the hands of the FBI. (His fellow terrorist will later call him “the stupidest, the stupidest, the stupidest of God’s creatures.”) The mastermind, Ramzi Yousef, gets away. Yousef, the most dangerous terrorist in the world, is now hiding out overseas and planning even deadlier attacks.  Back in New York, the FBI convinces Salem to rejoin the terror cell. He does, and becomes the personal assistant of Omar Abdel-Rahman (a.k.a. the Blind Sheikh). One of Salem’s jobs is to communicate by fax with a Saudi financier named Osama bin Laden. Then Salem learns that the cell is planning an attack designed to topple city landmarks and kill thousands.
