Zama Zama (2012)

Underground, where there is no light, the truth of a man is hard to hide.

In South Africa's gold-mining region is the subterranean dimension of the Zama Zama, illegal miners that make a living by mining the ore in both operational and abandoned mine shafts. "Zama Zama" is the personal narrative of two brothers: Malcolm, a successful businessman in the mining industry; and his long-lost brother Joseph, one of those who work in the underground tunnels--playing off against the tension of the mines' punitive actions against these miners.
