Decoder is a bizarre cyberpunk film that emerged from the German counterculture of the early 1980s. The film is based on the work of William S. Burroughs, who also has a small role in the movie. The intense, violence-inciting soundtrack features artists such as Soft Cell and Einstürzende Neubauten. F.M. Einheit, former percussionist of the latter band, plays the lead role in the film.
