Summer, 1984. 50,000 people gather in front of the Reichstag in Berlin, to marvel at the vast firework show entitled "The World and the Counter-World or Tumbling through Dreams" presented by André Heller, the total-artist from Vienna. 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, the Wall and the Brandenburg Gate nearby. 136 loudspeakers supply a resonant background. Historical documentary films and photographs (of the proclamation of the Weimar republic in 1918, the Reichstag fire, the Russian conquest of the Reichstag after the Second World War, etc) transform the event into a spectacular illustration of German history.
