This gripping series chronicles the events leading up to the 9/11 attacks and the escalating tensions between the FBI and the CIA in the years leading up to the tragedy.

The Looming Tower traces the rising threat of Osama Bin Laden and Al-Qaeda in the late 1990s and how the rivalry between the FBI and CIA during that time may have inadvertently set the path for the tragedy of 9/11.

The series follows members of the I-49 Squad in New York and Alec Station in Washington, D.C., the counter-terrorism divisions of the FBI and CIA, respectively, as they travel the world fighting for ownership of information while seemingly working toward the same goal - trying to prevent an imminent attack on U.S. soil.
