Watch She Walks by Night for Free: How to Stream the Movie Online at 123Movies. . Based on an actual post-war murder in Frankfurt, this standard docudrama by Rudolf Jugert is a serious treatment of the story as compared to the earlier, satirical film The Girl Rosemarie. The history of the case of Rosemarie, a hooker, and how she came to be strangled in her apartment is not completely clear. One of the suspects in the case was first charged, later acquitted, but never really free of an aura of culpability. British actress Belinda Lee plays the title role with her voice dubbed over in German.
