The film consists primarily of slow motion and time-lapse photography of cities and many natural landscapes across the United States. The visual tone poem contains neither dialogue nor a vocalized narration: its tone is set by the juxtaposition of images and music. In the Hopi language, the word Koyaanisqatsi means 'crazy life, life in turmoil, life out of balance, life disintegrating, a state of life that calls for another way of living, and the film implies that modern humanity is living in such a way. The film is the first in the Qatsi trilogy of films: it is followed by Powaqqatsi (1988) and Naqoyqatsi (2002). The trilogy depicts different aspects of the relationship between humans, nature, and technology.
