It's been nearly two years since the Benghazi attack that left four Americans dead and many questions remain. In a new documentary, Bret Baier ​uncovers the smoking gun of Benghazi and takes you inside the events on the ground, getting firsthand accounts from American security operatives who fought the battle.

What unfolded on the fateful night of Sept. 11, 2012 at the U.S. consulate and a nearby CIA annex?

The special hour is based on the new book by Mitchell Zuckoff, “13 Hours: The Inside Account of What Really Happened In Benghazi."
