Pirates (S02E08)

A new breed of pirates is terrorizing merchant seamen in the South China Sea - one of the most important shipping lanes in the world. They're on the hunt for black gold, targeting fuel tankers passing through. Local enforcement agencies are hot on their heels. But pirates have the advantage in international waters, where maritime law prevents coastguards from breaching borders. With 25% of the world's oil supply at stake, global groups bring in specialists to penetrate the pirate network. These investigators track phantom ships in search of middlemen making the deals. Their clients remain in the shadows; multi-millionaire moguls after a monopoly on oil. (National Geographic)
