Footage of planes crashing into buildings. The buildings eventually collapse and there are thousands of implied deaths.

Prior to the collapses, people are seen jumping/falling from the towers.

Some "sh*t"s and "crap"s.

Some people seen smoking in the background (after all, this is filmed on the streets of Manhattan). No alcohol or drugs.

9/11 transformed downtown Manhattan into a war-like zone, and the documentary presents this with striking accuracy. People's reactions and the events themselves are presented in a very raw and striking manner. This is not a sanitized depiction of 9/11 by any means.

The whole film is intense and frightening.
