Auschwitz did not spring from a single order; it was designed, budgeted, and built by ordinary civilian firms working alongside the SS, and this film traces that paper trail through KGB archives released after the Soviet collapse. Historian Gerald Fleming and architect Robert van Pelt work through construction records, blueprints, and correspondence showing German engineering companies competing for contracts to build crematoria and gas chambers, treating the camp as an infrastructure problem to be solved rather than a crime to be hidden. The film follows the site's expansion in stages, from a converted army barracks to an industrial killing complex, matching each enlargement to a surviving document: a requisition, a technical drawing, a letter negotiating price. What emerges is less a story of fanatics than of contractors and draftsmen doing routine work for a client, which is precisely the point van Pelt and Fleming keep returning to. The camp's own architecture becomes the evidence, drawing a direct line from office correspondence to the number of bodies a furnace could process in a day.
