A Jewish victim of Nazi human experiments fights against the Nazis and her race, which hates her because she gave birth to Hitler’s son.
SARA ends in a Nazi transit camp and gives birth to a newborn, identified as Hitler’s son, a product of artificial insemination. Major CONRAD’s research reveals Sara’s grandparents as Jews and BERTHA, Conrad’s killing machine, turns a once-proud Aryan Sara into a Jewish mother with no way to escape from Conrad’s camp.
Sara joins other prisoners and discovers identical twins, delivered by JOSEF MENGELE, to smuggle through them diamonds, stolen from Jews. Sara’s escape attempt convinces prisoners to trust Sara and to reveal her their escape tunnel while Sara’s protect Mengele’s twins, which forces Bertha into overdrive and almost kills Sara. The guards flee from the camp and leave its inmates in the hands of Bertha, whose goal is to kill as many Jews as possible, but only until she discovers the diamonds in the twins’ bellies and unites Sara with Sara‘s daughter ADA, the camps newest prisoner.
Sara plans an escape and discovers that Bertha locked down the camp protected by an electrified fence. She uses what she learned from her husband, and shows the prisoners the way out of this hell while Bertha and Sara end in a final confrontation in which they both die. Sara’s sacrifice enabled other prisoners a safe escape with the twins and the diamonds.
