The film depicts in virtually real time the New York-based events of the September 11 attacks primarily using raw video footage from mostly amateur citizen journalists. The documentary is accompanied by an 18-minute documentary short called I-Witness to 9/11, which features interviews with nine firsthand eyewitnesses who captured the video footage on camera.
According to this film, most of the archival video footage was in possession of the U.S. government but was released to History years after 9/11.
