Mischling

It's 1944 when the twin sisters arrive at Auschwitz with their mother and grandfather. In their benighted new world, Pearl and Stasha Zagorski take refuge in their identical natures, comforting themselves with the private language and shared games of their childhood. As part of the experimental population of twins known as Mengele's Zoo, the girls experience privileges and horrors unknown to others, and they find themselves changed, stripped of the personalities they once shared, their identities altered by the burdens of guilt and pain. That winter, at a concert orchestrated by Mengele, Pearl disappears. Stasha grieves for her twin, but clings to the possibility that Pearl remains alive.
