Love, It Was Not (2020)

A tragic love story between a prisoner and her captor. 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 saved hers, along with some of the people closest to her?
