Midway through Shahar Rozen's 1998 documentary Liebe Perla, the German disability rights activist and researcher Hannelore Witkofski is shown visiting the home of Wilhelm Brasse in Żywiec, Poland, not far from the town of Oświęcim and the former National Socialist killing center and labor camp complex Auschwitz-Birkenau. Witkofski has been charged by her friend, the Auschwitz survivor Perla Ovitz, with a mission: to locate film footage taken of Ovitz and her family, “the Jewish ‘Lilleput Troupe from Hungary,’” during their imprisonment in Auschwitz. As Ovitz describes earlier in the film, the SS doctor Josef Mengele, who was notorious for his deadly, pseudoscientific experiments on prisoners, took an interest in the family of entertainers because of the high rate of dwarfism within it; in fact, the Ovitz (Ovici) family was “the largest recorded dwarf family in the world.” The Ovitzes were also, according to the United States Holocaust Memorial Museum, “the largest family to enter Auschwitz and to survive intact,” a phenomenon that Perla Ovitz, herself a little person, attributes to the value that the family held for Mengele's medical experimentation. At the outset of Liebe Perla, Ovitz stresses to Witkofski that she cannot criticize Mengele, because she feels she owes her survival to him; but at the same time, she describes a particularly painful and humiliating experience in which she, along with her family, was forced by Mengele to stand naked for five hours in front of a panel of doctors while being filmed with a movie camera. She then bids Witkofski to find the film that resulted from this experience and, if possible, to destroy it. Rozen's documentary focuses on Witkofski’s search for the lost footage, a quest that includes, along with what Sara Eigen describes as Witkofski's “road trip to the archives,” her aforementioned visit to Brasse, now an elderly man, whom Witkofski interviews in a local restaurant. Witkofski hopes that Brasse can give her some clue about the origins or current whereabouts of Mengele's footage of the Ovitzes. Although he acknowledges that it is possible that his then-boss or someone else participated in the filming of the family, however, he himself is able to tell her nothing—“nicht ein Wort” (not one word)—about it, since as he says, “ich war ja nicht dabei” (I wasn't there). Witkofski's visit with Brasse yields no information whatsoever about the missing footage.
