Ultrarealistic documentary footage. A guided tour of the Penitenciária do Estado de São Paulo, mid-1930s — a small group of visitors that includes a young French academic — Lévi-Strauss — being shown the facility by a prison official in a dark uniform. The group moves through the central corridor, the official explaining the classification system and the rehabilitation program. Lévi-Strauss observes attentively. The prison in this period still functions approximately as designed. Warm afternoon sidelight through the corridor windows, the tour group in clear light. Visual-only scene. No music. Clean frame.
