It's 1985 and the cold war between the U.S. and the USSR continues. At the CIA Sandy Grimes must make a decision - whether to proceed with a payment in Moscow to one of their most valuable intelligence assets, KGB officer Leonid Poleschuk. A CIA agent from the US Embassy tries to make the drop but both he and Poleschuk are arrested. In reviewing the events, Sandy realizes that they were set up and the KGB obviously knew about the drop long before it happened. She subsequently learns from her superiors that they have recently been losing assets at a rapid pace and they believe the KGB has somehow penetrated the Agency. Unbeknown to all of them, they have a mole in their midst, their colleague Aldrich Ames.
