So war die DDR

'GDR Secret' sheds light on the lesser-known traces of the GDR - the shadowy realms of a state in which as much as possible was done by the official authorities to ensure that there was as little private as possible, but all the more secret. Paul Bergner, an expert on these shadowy realms, goes into the secret bunker worlds of the Politburo, the military and the Stasi accompanied by an MDR team. Former commanders give authentic accounts of life in the nuclear-safe shadow realms. People who lived in the immediate vicinity of these bunkers tell what they knew or thought they knew about the purpose of the bunker constructions. Even with the necessary distance, these bizarre underworlds evoke amazement and horror in equal measure. And so these reports open thick steel doors to the absurd shadow worlds of the Cold War.
