Zero Hour - the final two hours of the Inside 9/11 - captures the horror and the heroism witnessed on September 11, 2001, and takes you into the last moments of those who died that day and the thousands of others who survived the tragedy but will always live with the battle scars from a day we will never forget.

Osama bin Laden has finally been brought to justice, but Al Qaeda is still going strong. For bin Laden, 9/11 was just the beginning-the attack was designed to spark a revolution and create a whole new generation of men willing to wage jihad against America. But ten years later, these same men have eclipsed bin Laden on the global stage. And their call to jihad has gone viral with terror groups using the Internet to recruit and radicalize future attackers in the name of Allah.

War on America opens with the dramatic 1993 World Trade Center bombing and tracks terrorist activities aimed at U.S. targets throughout the 1990s leading up to the horrific morning of September 11, 2001. With each successful attack, al Qaeda becomes more emboldened. With each failure of the U.S. government to respond or stop their activities, the organization and the legend of Osama bin Laden grow.
