Deckname Schlier

From October 1943, a secret V2 rocket armament plant was set up in the cellars of the Zipf brewery in Redl/Zipf in Upper Austria - and at the same time a satellite camp of the Mauthausen concentration camp was established. At the end of the war, all documents and memories were destroyed - until the accidental discovery of the ‘insignificant’ bunker brought the story to light. The long silence comes to an end - thanks in part to the filmmakers' research.
