World on a Wire (German: Welt am Draht) is a 1973 West German science fiction television serial, starring Klaus Löwitsch and directed by Rainer Werner Fassbinder. Shot in 16 mm, it was made for West German television and originally aired in 1973 in ARD as a two-part miniseries. It was based on the 1964 novel Simulacron-3 by Daniel F. Galouye. An adaptation of the Fassbinder version was presented as the play World of Wires, directed by Jay Scheib, in 2012.[ 2]
Its focus is not on action, but on sophistic and philosophic aspects of the human mind, simulation, and the role of scientific research. A movie based on the same novel titled The Thirteenth Floor starring Craig Bierko was released in 1999.
In the present day, the Institute for Cybernetics and Futurology's (Institut für Kybernetik und Zukunftsforschung) new supercomputer hosts a simulation program that includes an artificial world with more than 9,000 "identity units" who live as human beings, unaware that their world is just a simulation. Professor Vollmer (Adrian Hoven), who is the technical director of the program, is apparently on the verge of an incredible secret discovery. He becomes increasingly agitated and anti-social before dying in a mysterious accident. His successor, Dr. Fred Stiller, has a discussion with Günther Lause, the security adviser of the institute when the latter suddenly disappears without a trace before he is able to pass on Vollmer's secret to Stiller. More mysterious still is the fact that none of the other IKZ employees seem to have any memory of Lause.
Meanwhile, one of the identity units in the simulation attempts suicide. This unit is deleted by Stiller's colleague Walfang to keep the simulation stable. To investigate the reasons for the suicide, Stiller enters into the simulated world to interview the contact unit. The unit, called Einstein, is the only identity unit that knows the "world" is a simulation, and this is necessary to run the program. In an attempt to become a real person, Einstein switches his mind into Walfang's body while Stiller is in contact with the simulated world. Einstein gives Stiller an explanation for the mysteries, vanishing memories, and vanishing persons, telling him that Stiller's "real world" is nothing but a simulation of the real world, which is one level above.
