The director of an art museum in Thuringia and an art dealer from Constance entered into an extremely lucrative business relationship. Director Trützschler illegally supplies Ms. Münzenberg with valuable works of art, which she smuggles into West Germany through an intermediary, abusing the transit routes. The business flourishes until they both fall into the CIA's intricate web. They are put under pressure and used to recruit a scientist from Jena. Will the GDR security forces succeed in thwarting the CIA's espionage operation...?
