In her essay film, Eva Hiller illustrates the nightly infrastructure of a large city, using Frankfurt am Main and Berlin as examples. Just as pet reptiles gone feral are reported to populate New York's sewers, so too is there bustling activity – often invisible to outsiders – when darkness falls on Germany’s metropolises.
Unfortunately the movie Invisible Days, or the Legend of the White Crocodile is not yet available on Disney Plus.
