Where in Greek mythology, the earth mother Gaia gives us the topos of the city, Nyx the goddess of the Night gives us the inner realm. The progeny of Nyx, a potent crowd embodying human experience include old age, rage, strife, and friendship. Thanatos, the god of quiet death, his twin Hypnos and his wife Pasithea, the goddess of hallucination, begin the Odyssean journey of a young man from Kreuzberg along the U7 line to Spandau. The cast is made up of friends and acquaintances, mainly Kurdish, who have a parallel, if unwritten, experience of the recent history of Berlin. Kreuzberg, now semi populated with young artists and trendsetters from around the world, in the 1970s and 80s was a haven for Kurdish immigrants. The U7 line, designed by Rainer Rümmler, architectural engineer for the BVG during the Cold War, follows the river Spree. In Nyx the U7 becomes the river Lethe, the river of forgetfulness. The plot of the film is based on anecdotes of Kurdish life in Berlin and Turkey, especially from Garip Özdem, who also kindly allowed the use of the additional scenes from Kurdistan of the goat sacrifice.
