They were dubbed "The Lackawanna Six" and they were American citizens accused of aiding Al Qaeda and having personally met with Osama bin Laden. The case was hailed as a victory in the war on terrorism. Combining the forces of the FBI and CIA under the new powers of the Patriot Act, the federal government brought all its counterterrorism resources to bear on the "Lackawanna Six." But were these Americans really an Al Qaeda "sleeper cell" ready to strike at bin Laden's command? Or were they, as one alleged terrorist claims, merely unwitting pawns whose desire to become more deeply immersed in Islam landed them in the wrong place at the wrong time?

FRONTLINE and The New York Times join forces to go deep inside the war on terror at home in "Chasing the Sleeper Cell." With remarkable access to top government officials and counterterrorism investigators- and featuring an exclusive interview with a member of the alleged terrorist cell- the report takes viewers inside a secret national security investigation to witness how America's intelligence agencies pursued an alleged Al Qaeda cell operating in the United States.
