Miklós Nyiszli était un prisonnier juif du camp de concentration d'Auschwitz. Volontaire pour offrir ses compétences médicales, il s'efforça d'aider les malades avec des fournitures rudimentaires. Ses aptitudes attirèrent l'attention de l'officier SS Josef Mengele, qui le transféra dans une salle d'opération spécialement construite au sein d'un crématorium. Nyiszli se retrouva impliqué dans les sombres interventions qui y furent menées, témoignant des circonstances déchirantes du camp.

After what I heard I braced myself to see something shocking, but the scene I now encountered surpassed all my imaginings..."
