Once upon a time in post-war Rome, 13-year old Aurora, a gifted pianist, is the daughter of Valerio, a brilliant conductor.
After Aurora’s mother died, Valerio hired Irene, a single mother of two girls, to run the household. To Aurora’s regret he decides to marry Irene. One day, Aurora happens to meet the boys next door, Freddy and Sebastian, the sons of a wealthy Italo-Austrian family. Freddy is an easy-going chap, though sometimes a little bit arrogant. His brother Sebastian is kind and shy, with a great ability to listen to and understand people, which makes him win Aurora’s heart.
However, Aurora’s life is shattered when her father suddenly dies. Irene, the unloved stepmother, lays hands on the family’s assets and turns her late husband’s villa into a hotel. Aurora is unable to claim her right to inheritance until her 21st birthday. Irene makes her give up schooling and piano playing. Instead, she has to work as a maid in the hotel. Irene’s own daughters, Lucia and Teresina, never miss out on an opportunity to tantalize the poor girl.
Years later, Aurora has become a young woman. She secretly plays the piano on an improvised keyboard on the windowsill. The employees of the hotel keep her company and became her surrogate family.
One day Mrs. Cooper arrives at the hotel, a rich American former star of silent films, and it turns out that it is the grandmother of Aurora.
During a masquerade ball Aurora finds Sebastian, who she loved in childhood. He does not recognize her, and she did not have the strength to come forward because she knew that he is engaged to Tina, daughter of the man with whom Sebastian is in talks of business, and who intends to marry on the advice of his father for purely economic purposes.
Meanwhile, the stepmother has discovered that Mrs. Cooper is the grandmother of Aurora, and wants to prevent Aurora from realize all her dreams and finally find happiness.
Eventually, with the help of two employees of Aurora she manages to redeem herself and get everything that had been taken by her stepmother and stepsisters.
Thus began a new life for Aurora of music, passion passed on to her by her father conductor and pianist mother, and love for her young Austrian prince Sebastian.
