I found this interesting and dramatic in the way real life can be. It's from a documentary which was being made on a trauma hospital in London last year., St. Mary's. It starts during a routine meeting of hospital execs, which is interrupted when they're put on notice of a 'major incident' at Westminster Bridge and that they will be receiving a number of trauma cases. It goes through how they organize for it, the reception and treatment of the injured, and then how the injured recover, both physically and emotionally.
