This film represents the only work created by the NCM (New Militant Cinema). Conceived and directed by Giancarlo Buonfino. The film was shown on a 16mm projector in universities, factories and meetings. Although it was a self-produced film, its quality was professional for its time, G. Buonfino worked for over a year to make it, learning to use stop-motion animation on a large 35mm "vertical" film made available to him by Giulio Cingoli's ORTIFILMSTUDIO.
