East Berlin in the early summer of nineteen sixty-eight. Alexanderplatz is a huge building site: socialism is getting a makeover and the GDR capital is set to become a modern showcase of the Republic.
In June 1968 18-year-old Toni Krahl, who will later front the rock band City, travels to Prague and is impressed by what he finds there: "socialism with a human face".
However, on 21 August 1968 half a million soldiers from the Warsaw Pact countries invade the CSSR, crushing the Prague Spring. The authorities in East Berlin welcome the intervention and convict 1,200 people who take to the streets in protest, including Toni Krahl.
