Summer 1984. An audience of 50.000 people gathers at the Reichstag, Berlin, to marvel at the vast firework show entitled "The World and Counter World, or Tumbling through Dreams", presented by André Heller, the "total artist" from Vienna. Historical documents transform the event into a spectacular illustration of German history, which appears to have become permanent with the division of the world into East and West. André Heller plans to set off 40.000 rockets, squibs and flares - 25 tons of explosives in all - at a place which is packed with historical associations, with the Wall and the Brandenburg Gate nearby. 136 loudspeakers supply a resonant background.
