East Berlin, early 1980s: Ludger is hired by the Stasi to spy on the oppositional arts scene in Prenzlauer Berg. But when he falls in love with the mysterious Nathalie, he has to choose between a life as a celebrated underground poet and his career as a Stasi agent. A choice that will turn back on him 30 years later.
In October 1989, the part of the West Berlin borough of Kreuzberg called SO 36, had been largely shut off by the Wall from the rest of the city for 28 years. A lethargic sub-culture of students, artists, bohemians and barflys had flourished among crumbling buildings. Part of that microcosm is barkeeper Frank, semi-formally called 'Herr Lehmann' by friends and patrons. He hangs out drinking, sports utter disregard for anything beyond SO 36 and lazily pursues an affair with cook Katrin. His lifestyle is gradually disturbed, when his parents show up for a visit, things go awry with Katrin and his best friend Karl starts to act strange. Meanwhile, political turmoil mounts on the other side of the Wall.
