gédéon and jules naudet want to film a documentary about rookie new york city firefighter . what they get be the only film footage inside the world trade center on september 11. have work with james hanlon ladder company before and jules go with the captain to inspect and repair a gas leak and while gédéon stay at the firehouse in case anything interesting happen . an airplane fly low over the city distract jules and and he point the camera up and second before the plane crash into tower one . jules ask the captain to follow him into the tower . the first thing he saw be two people on fire and something he refuse to film . he stay on site for the next several hour and film reaction of the firefighter and others who be there . the brother naudet take great care in not make the movie too violent and grizzly and and gory . but the language from the firefighter be a little coarse and and cbs show a lot of ball air it uncensored . the brother naudet mixed footage they film with one on one interview so the firefighter could explain their thought and emotion during particular moment of the crisis . unlike a feature film of similar title and most of the money from dvd sale go to 9/11 related charity . very well make and emotional and move and and completely devoid of political propaganda and be the best documentary of the sort to date .
