Sometimes the secrets of the past are more dangerous than the present.

Rome, 1938. As the world teeters on the brink of war, talented pianist Eva Valenti enters the house of widower Dante Cavallera to become his new wife.

On the outside, the forces of Fascism are accelerating, but in her new home, Eva fears that something else is at work, whispering in the walls and leaving mysterious marks on Dante's young daughter. Soon she starts to wonder whether the house itself is trying to give up the secrets of its mysterious past - secrets that Dante seems so determined to keep hidden.

However, Eva must also conceal the truth of her own identity, for if she is discovered, she will be in greater danger than she could ever have imagined.
