1991 wird der Regierende Bürgermeister Eberhard Diepgen in Berlin wiedergewählt. Er und der Fraktionsvorsitzende der CDU, Klaus Landowsky, heimlicher Strippenzieher der Berliner Politik, träumen davon, Berlin wieder zur Weltmetropole zu machen.
Deuxième volet : redevenue capitale de l'Allemagne, selon le traité d'unification du 31 août 1990, Berlin entre dans une phase d'euphorie avec la décennie qui s'ouvre.
In 1991, Governing Mayor Eberhard Diepgen is re-elected. Alongside CDU leader Klaus Landowsky, he dreams of restoring Berlin as a world metropolis. As East Berlin’s industry collapses and mass unemployment hits, West investors seek profit, taking big risks. Techno pioneers and squatters seize empty spaces for their utopias, while the Love Parade grows into a sensation. Berlin becomes the capital and bids for the 2000 Olympics. But the poor city’s citizens revolt, and the left-wing scene pushes back. Meanwhile, far-right violence rises in the East, clashing with the image of an international city. Still, politicians press on, casting their vision in concrete at Potsdamer Platz. Yet Europe’s biggest construction site can’t mask the storm clouds gathering over the new capital.
