Flamboyant and full of life, Helena Citron is taken to Auschwitz as a young woman, and soon finds unlikely solace under the tutelage of Franz Wunsch, a high-ranking SS officer who falls in love with her and her magnetic singing voice. Risking a certain execution if caught, their forbidden relationship went on until her miraculous liberation. But when a letter arrives from Wunsch*s wife, thirty years later, begging Helena to testify on Wunsch*s behalf, she*s faced with an impossible decision: will she help the man who brutalised so many lives, but s*ed hers, along with some of the people closest to her?
