Moebius is a 1996 Argentine science fiction film directed by Gustavo Mosquera and starring Guillermo Angelelli, Roberto Carnaghi and Annabella Levy. It is based on the classic short story A Subway Named Mobius, by Armin Joseph Deutsch. The film is set in the Buenos Aires Underground, in a dark and dystopian Buenos Aires.
In an attempt to hide the incident from the public, the director of SBASE contacts the engineering firm responsible for the construction of the line where UM86 went missing in order to investigate the incident. The firm then sends a young topologist Daniel Pratt, rather than an experienced engineer, which displeases the director.Upon looking for the original plans of the line at a national archive, Pratt discovers that they are missing and were taken away by his former lecturer at the University of Buenos Aires, Hugo Mistein. After looking for him at the University, another professor tells Pratt that Mistein retired some time ago and has not been seen or contacted for a considerable period. ........
