9⁄11 is perhaps the defining event of the contemporary era. Broadcast internationally, it is a moment in modern history that everyone over a certain age feels that they lived through. This film takes the form of two intertwining narratives: the two hour period when terrorists attacked the Twin Towers, the Pentagon, and Flight 93; and the story of the 20 years that have passed since. Told by a mix of British and American contributors, this is a deeply personal film about survival and loss. Using a combination of testimony, and personal and public archive, the day unfolds almost as if in real time. Lyrical contemporary scenes explore how the lives of individuals continue to be affected by moments that took place in that two hour period, and through the indelible imprint on their lives, an impression is generated of the impact that that day had on the wider world.
