Jeremy is an air-brush artist. In the basement of his house he has set up a studio where he passionately works, drawing inspiration from listening to music, watching TV, reading books and using images from magazine cuttings. Jeremy has a stereo player with supernatural powers. The different styles of music played create fantasy environments where anything is possible. He decided to use the stereo player to murder his girlfriend Saskia. Initially he appears to be successful, but what follows is a series of terrifying events (including the recreation of Saskia as a technological demon) that have horrific consequences.
