A hundred and two minutes passed between the first plane's impact into North Tower of the World Trade Center on 11 September 2001, the second plane's attack on South Tower, and the collapse of both buildings.
In that time, people around New York reached for their cameras.
This documentary joins together hundreds of pieces of footage and audiotape into a single, seamless historical record, much of it never seen before.
It is an intensely personal and new perspective of the tragedy, telling that morning's events in real time, as they were experienced by people around New York.
