In their documentary film, the three filmmakers Lea Sprenger, Franca Pape and Amelie Vierbuchen set out to find material about the Kalk chemical factory in Cologne. During their research at the Archive “Rheinisch-Westfälisches Wirtschaftsarchiv zu Köln”, they meet archivist Dr. Christian Hillen, who has a lot to say. While the archivist struggles with the 16mm film, the filmmakers dig through the chaos of sources and capitulate to the resistance of the material. Who decides which stories are saved or thrown away? A fast paced film about searching, throwing away, about gaps and mistakes and about one's own inability, which is repeatedly met with self-irony.
