The Nazis have forced Natia and Teodor from their Polish farm to a labor camp. Separated, Natia is chosen to be the housekeeper for the camp's overseer, and her husband Teodor is sent to work in the factory. Despite the strict camp rules—and the consequences for disobeying them—Natia finds a way to communicate with Teodor by sending messages through song as she passes Teodor's dormitory. But then Natia finds a Jewish orphan on the overseer's doorstep. She is determined to protect the boy and raise him as the child she and her husband were unable to bear—but if her German captors discover how much she's hiding, both she and Teodor may pay the ultimate price.
