Assembled entirely from raw footage shot as the September 11 attacks unfolded, this film drops narration altogether and lets the recordings speak: network news feeds, home camcorders, security cameras, and radio transmissions from police and fire dispatchers. The 102 minutes of the title run from the first plane hitting the North Tower to the collapse of the South Tower, tracked in real time so the confusion, the wrong guesses, and the delayed realizations play out exactly as they did on the ground in Lower Manhattan. Firefighters climb stairwells while dispatchers relay updates that are already out of date. Bystanders on the street film the towers burning, then run as debris and dust fill the frame. Without a host or historical framing, the film functions as document rather than explanation, showing what people actually knew, saw, and said minute by minute rather than what was later understood. The absence of hindsight is what makes it disorienting to watch.
