This is the extraordinary tale of intrigue and espionage that begins with the first attack on the World Trade Center in 1993. A riveting minute-by-minute account shows what was going on behind the scenes on 9/11. There was confusion in air traffic control, a failure to promptly notify the military about hijacked planes, and a breakdown in communications around the President. The documentary reveals the long, secret war waged against al-Qaeda from the White House, the CIA and the FBI, and examines the intelligence failures that allowed the 9/11 plot to happen.
