Kathryn Bolkovac was a UN monitor in Bosnia after the war and while the UN and their contractors were policing the country. While there she found that many of the UN personnel and companies were complicit in human and sex trafficking.
The film follows her struggles from the breakdown of her marriage back in the States to being hired to work for the UN to help with the work in Bosnia. Her first success was in getting a prosecution against domestic violence through for a despised Muslim woman.
She then discovered that many of the police officers hired by the UN were corrupt and engaged in the sex trade either as clients or as protectors. The rest of the film follows her attempts to get this exposed and the resistance she faced, and the personal danger she had to undergo.
Eventually, because of her activities she was fired and managed to get a successful lawsuit through for unfair dismissal in British courts and bring to the public's attention the plight of those subject to human trafficking, and the UN's complicity in the trade.
It is a harrowing story and some of the violence against the girls involved in the trade is very graphic. The film focuses on Kathryn’s story and it is rather unsatisfactory that we still find UN forces involved in rape, assault and other abuses while protected by diplomatic immunity. The latter should be stripped from anyone who is guilt of such horrific crimes, of course, but that is not how the world works these days.
