Margarete stumbles out of the ruins of a bombed-out house. The dust settles around her like snow. A member of the recovery team asks her if she needs help. Margarete slides her eyes to where the hated yellow star was shining a moment ago, musters up the courage to say, “Yes.”

Berlin, 1941: Margarete Rosenbaum works as a maid for a high-ranking Nazi officer. When his house is bombed, she is the only survivor. And when she is also mistaken for an officer's daughter, she decides to seize the opportunity...

With her new identity, she leaves her Jewish heritage behind and seems to be relatively safe until she is tracked down by the son of her former employer and also her "brother", SS officer Wilhelm Huber. But he strangely does not want to reveal Margaret's deception. She only insists on living with him in Paris and continuing to pretend to be his sister. Margarete is worried about revealing what Wilhelm might want in return. Can she trust a Nazi officer with the only thing she has left... safety, life, and even her heart?
