A four-part series that reveals how a secret pact formed a cartel that controls the world's oil. On August 28, 1928, in the Scottish highlands, began the secret story of oil. Three men had an appointment at Achnacarry Castle - a Dutchman, an American and an Englishman. The Dutchman was Henry Deterding, a man nicknamed the Napoleon of Oil, having exploited a find in Sumatra. He joined forces with a rich ship owner and painted Shell salesman and together the two men founded Royal Dutch Shell. The American was Walter C. Teagle and he represents the Standard Oil Company, founded by John D. Rockefeller at the age of 31 - the future Exxon. Oil wells, transport, refining and distribution of oil - everything is controlled by Standard oil. The Englishman, Sir John Cadman, was the director of the Anglo-Persian oil Company, soon to become BP. On the initiative of a young Winston Churchill, the British government had taken a stake in BP and the Royal Navy switched its fuel from coal to oil.
