The plot takes viewers to various places in Europe, including Prague, Erfurt, Frankfurt/Main and even Tenerife. And the title "The Blonde Geisha" turned out to be a nickname for the film's heroine, who had once been called that by her school friend Andreas. At the time, there was more than a hint of romance between the two, but then they lost sight of each other. Now, all of a sudden, a reunion in Prague! This would be a chance for Erika and Andraes to start afresh, but the two are not alone in the Czechoslovakian capital, as if on an island. Instead, the businesswoman from West and the research engineer from East find themselves in the sights of shady people who do not shy away from crime in order to achieve their goals, and so the two main protagonists find themselves in increasingly dangerous situations.
