In 1929 Berlin, the progressive editor-in-chief Bornstein is on trial for libel. An article in his magazine attempted to uncover the role that Reichsanwalt Jörns had played ten years earlier in the "clarification" of the murders of Rosa Luxemburg and Karl Liebknecht. The article explained that the then court martial judge knowingly covered up for the murderers and delayed the trial. At the trial, the testimony of witnesses succeeded in proving the truth of the publication and exposing those behind the murders as those who were preparing fascism.
