In 1955, Max Haffner, burdened with guilt, puts together a risky photo exhibition from the work of his long-time friend, Greta Anckermann, in the hopes that she will return from exile to Vienna. His 8-year-old daughter, Patrizia, takes in the glossy prints and listens to her father describe Greta, and her Leica camera, in mythical terms, becoming enchanted with her legend.

Thirteen years later, in 1968, novice journalist Patrizia finds Greta, convincing her to tell her story. She hopes to reinvent Greta, remind the world that she existed; Greta hopes to expel her demons. As the incredible story unfolds, Patrizia hears shocking truths about Greta's role in history, and Max's role in Greta's life.

Patrizia vows to get the truth out of Greta, but it may be more convoluted than she imagines.
