The film utilizes a montage that juxtaposes these images of ghetto Jews with images of rats to draw an analogy between the migration of Jews from Eastern Europe with the migration of rats. For example, one of the shots shows a pack of rats emerging from a sewer, followed by a shot of a crowd of Jews in a bustling street of the Łódź Ghetto. Close-ups of those in the crowd reveal sickly, malformed facial features. The narrator states that, as rats are the vermin of the animal kingdom, Jews are the vermin of the human race and similarly spread disease and corruption. Unlike rats, however, the narrator continues, Jews have the uncanny ability to change their appearance and blend into their "human hosts." A scene depicts four bearded men in traditional religious Jewish clothing, then shows them shaved and in modern business suits, while the narrator explains that only a "trained eye" can distinguish their Jewish features.
