A letter from Viktor Brack, written in flat bureaucratic language, sets the tone for this account of the physicians who ran the medical machinery of Auschwitz. The film traces how doctors moved from selecting prisoners on the ramp to conducting experiments in the camp's medical blocks, using wartime documents, internal correspondence, and postwar testimony to reconstruct decisions made by men trained to heal. Figures like Brack, whose signature appears on orders for the killing program, illustrate how administrative language was used to authorize mass murder. The film examines the selection process, the pseudo-scientific experiments performed on inmates, and the chain of command that linked camp doctors to the wider apparatus of the Holocaust. Rather than treating these men as aberrations, it follows the paper trail showing how medical authority was folded into a system built for extermination, and how the surviving records now serve as evidence of what happened inside the camp's clinics and barracks.
