Philip persuades her to take photos of the study in the home of United States Secretary of Defense Caspar Weinberger, so that the KGB can plant a listening device.

Stan finds Nina, telling her he knows that she's sending high-priced U.S. stereo equipment back to the Soviet Union; he blackmails her into spying on the Russians for the FBI.
