Rivkah gives birth to a daughter, Mimi, determined that her child will have a better life in America.

Frederick Winthrop, slum landlord, lives in one of Fifth Avenue‘s sumptuous mansions—and preys on young girls.

To avoid scandal, the Winthrops family offers Mimi a rare opportunity. While Lottie, now a bookkeeper in the employ of the Winthrops, wisely advises her, Mimi knows exactly what she wants. But as she rises to international fame, she must struggle with the secrets of her past and protect those she loves.
