The new work of renowned documentary filmmaker Gerd Kroske tells of the tensions between a subculture and a dictatorship and of a betrayal amongst friends. "Striche ziehen" portrays a former clique of punks out of Weimar in the mid-1980s. After several clashes with the authorities of the GDR, controls and spying, they left for West Germany – and planned a spectacular art performance symbolizing the crossed out plans of the regime: They travelled to West-Berlin to paint a white line all along the Berlin Wall. But the performance took a dramatic turn when East-German boarder guards abducted one of the friends and arrested him. Evidently, someone had informed the secret police... Gerd Kroske reconstructs the events of 1986 and interviews the betrayed as well as the betrayer. The result is an exceptionally complex reflection on guilt and forgiveness, and also a document of the social climate in the GDR shortly before its fall.
