Documentary series that reveals how a secret pact formed a cartel that controls the world's oil. Throughout the region's modern history, since the discovery of oil, the Seven Sisters have sought to control the balance of power. They have supported monarchies in Iran and Saudi Arabia, opposed the creation of OPEC, profiting from the Iran-Iraq war, leading to the ultimate destruction of Saddam Hussein and Iraq. At the end of the 1960s, the Seven Sisters, the major oil companies, controlled 85 percent of the world's oil reserves. Today, they control just 10 percent. New hunting grounds are therefore required, and the Sisters have turned their gaze towards Africa. With peak oil, wars in the Middle East, and the rise in crude prices, Africa is the oil companies' new battleground.
