In 1975, DFFB students search for traces of the labor movement of the 1920s in Charlottenburg's Zillestrasse. Wallstraße was one of the poorest residential areas in Berlin at the time and a stronghold of the German Communist Party (KPD). In detailed interviews, former KPD members talk about their organizational and propaganda work in the "house protection squads" and the street battles with the National Socialists. The documentary film Street in Resistance revives a chapter of the workers' movement that has received little attention in the West and also recalls the novel Our Street by writer Jan Petersen, published in exile in 1936, about everyday life in Wallstrasse.
