Afghanistan, 1981. The Soviet Union invaded Afghanistan in 1979, threatening to expand its huge hold of territory and edge closer to the rich oilfields of the Middle East. President Reagan decided to send CIA officers in to train Afghan rebels to fight against the Soviets. But he didn't want to tip America's hand, so he sent in a small team of undercover officers from the CIA's Islamabad station in Pakistan. Working in dark alleys and traveling on Pakistani military helicopters, Milt Bearden and his team of CIA officers gradually built a network to funnel arms and cash into Afghanistan and train the rebels to fight. Dodging bullets and risking their lives, the CIA officers became secret warriors fighting America's last battle of the Cold War.
