Greetings!
It has been many years since I saw that movie, but I'll try to get you started. "In a time in which women were little more than the possessions of their fathers and husbands, one woman found her strength and asserted her independence with her fingers on a piano keyboard, pouring out the depths of her soul through music." That may be a little over the top, but perhaps it will give you some ideas. I wasn't really sure how the target advertisement was supposed to fit in.
I'll be happy to help you with some editing once you start your rough draft.
Thanks,
