From its title, this is clearly an emotive documentary; members of the FDNY and others are interviewed about that terrible day, there is archive footage and a brief look at the origins of the brotherhood that lost a staggering 343 men as a result of the crashing of two of the four hijacked planes into the Twin Towers.

The first of their casualties was Danny Suhr, who at just 37 was an 18 year veteran; he was killed by a jumper.

We also see footage of the planes hitting the towers and of the towers collapsing, something all of us who recall that day will have already watched time and time again.
