Based on the true story of Gretel Bergmann who unwittingly became the biggest threat to the Nazi Party in 1936. Berlin was hosting the summer Olympic Games and Gretel was one of Germany's best gold medal contenders. She was also Jewish. Her skill and ethnicity undermined the Nazi belief that Aryans were the superior race, so the German authorities schemed to replace Gretel with another woman -- but "she" had a secret that, if uncovered, could be even more embarrassing to the Nazis.
