Go deep into Zimbabwe's Marange diamond fields and uncover evidence of torture camps and wide-scale killings. A torture camp run by Zimbabwe's security forces is operating in the country's rich Marange diamond fields. Now, soldiers and paramilitary police from Zimbabwe have broken ranks to speak out about a 2008 operation in which civilians working in the Marange diamond fields were massacred. Hear testimony from survivors and unearth evidence of the brutal and violent crackdown that leads directly to the security forces under the command of the Zimbabwean government. Also head to Hatton Garden, the jewelry district in London, to see whether a ban on conflict diamonds from Zimbabwe's Marange region is working. While the international community argues over whether these diamonds should be sold on the open market, this investigation asks President Robert Mugabe will ever face prosecution for these crimes.
