For microbiologist Dr. Wolf, it seems to come true when an American lawyer visits him to tell him about the death of his distant uncle in the USA. Wolf is to receive an inheritance worth millions, but on one condition: He must continue to run his uncle's factory in the USA. The natural scientist is also offered the prospect of a research position at Camp Detrick. But after the memorable visit, Wolf discovers a listening device in his apartment. When he informs the People's Police, more and more inconsistencies come to light.
