Sexpionage tells the stories of two women who were seduced by secret agents working for the East German intelligence service, the Stasi. At the height of the Cold War the Stasi would regularly despatch their agents to the West German capital, Bonn, armed with the task of forming long term relationships with single women working at embassies or government ministries. These women were unwittingly tapped for top secret information which was then passed on to the East. Both Gabriele Kliem and Margaret Hike had no idea that their lovers were spies until both women were arrested for treason. This film tells the story of the years they spent with their secret agent lovers and explores the feelings they are left with after the most significant relationships of their lives were revealed to be a sham.
