This eye-opening documentary illustrates the difficulties in controlling international fishing, as world fish stocks show signs of depletion. The Patagonia toothfish is becoming so valuable it is known as "White Gold" and has caused an explosion in fishing. The value of this oily, white fish lies in its desirability as a delicacy in restaurants throughout the East and the United States; it is four times the price of regular white fish. This explains why people take the risk of fishing for it illegally. South Africa is one of the countries trying to end unlawful fishing in their waters, but it is "like looking for a needle in a haystack." Environmental groups are concerned that over-fishing will place the toothfish at risk of extinction.
