For those who can't or prefer to not watch, it's a girl with part of her lower jaw (or at least the flesh) blown off apparently being assessed in a busy hospital. One tries to hold up her jaw, but the girl is sat down and then stood up again, so it dangles a bit. There appears to be a dead body on the floor in the background in the first part. In the last few seconds it goes to a different shot with the camera on the other side of the girl, and closer. It sounds as though she might be talking when the video ends.
