Radiokiller
Viewers interested in modern Crime cinema often explore Radiokiller because of its cast, story direction, and audience popularity.
Enemy secret services from the West had used modern technology for the "cold war", i.e. the confrontation with the Eastern Bloc, and developed a device called COMMINT 3-72. Its nickname was "Radiokiller". This weapon was not much bigger than a soccer and could be easily camouflaged on the territory of the GDR, for example as a fieldstone, the remains of a wall or a lump of earth. These enemy objects were inconspicuous on the outside, but packed with complicated inner workings, i.e. highly sophisticated microelectronics.
