In 2014, a number of busses carrying Mexican students were attacked, and 43 passangers disappeared. Drug cartels were involved, but also local authorities. No-one has yet been prosecuted for the crime. It's hard to conceive a more damning indictment of a failing state. This documentary looks into what happened, both at the time, and also in the subsequent investigation. Perhaps unsurprisingly, there are no clear answers, except for the conclusion that there are people in positions of power who do not want the truth to be told. It's not exactly fun viewing, but it's a story that needed to be broadcast. One can only hope that one day the relatives of the victims will learn what happened, and that ordinary Mexicans need no longer live in fear.
