A visionary and unpredictable piece of cinema that analyses the digestive process as a fundamental condition of human bodily existence. The film centres on five important texts on the boundary between the physical body and such an interiority. The Italian poet Dante Alighieri, the science fiction writer Octavia Butler and the French physiologist Claude Bernand are read. It is an intelligent, virtual reality-like documentary that combines the modern visual language of cinema with philosophical themes and, together with the musical fabric of the film, creates an exceptional experience.
