The film consists of a number of texts, which appear on the screen and on the soundtrack simultaneously. This written and spoken text contains a series of instructions for the projectionist on how to operate his machine. These dramatic interventions he has to perform, make visible how the machine works, which he controls. In fact, the audience does not see the film, but pays attention to the interactions between the screen (the score) and the projectionist (the performer). The film is a performance, in which the score is visible, while the performer remains hidden.
