Aldrich Ames: A Spy Like Us

S1, E5: Aldrich Ames was probably the most damaging mole in CIA history. In 1985, he single handedly shut down the CIA's eyes and ears behind the Iron Curtain by revealing to the KGB the name of every "human asset" that was secretly spying for the West. At least 10 agents were executed, and dozens were condemned to harsh prison sentences in the Soviet gulag.
