The film is "a hyper-real multi-angle DVD environment. Pan sonic, Mika Vainio and Ilpo Väisänen, are immersed in the imagery of the cathode which seems to live and infect their physicality over the course of three parallel films as they merge with their own extreme sound and into Quist's sinister vision."
