London, early 2000s: Anne is a young musician with two great talents; chello and lack of compromise. After a robbery on rehearsal day, Anne is forced to use an old case for her chello, one that has been in her family for generations. Or so she thinks.
A stumble in the middle of the street breaks the handle of the case, leading Anne to discover a key and an old photo reel buried inside the cover. The picture, old and barely visible only shows a street in Barcelona and a pair of twins. This discovery will lead Anne to uncover a past that she might have chosen to never figure out.
Now, Anne is in Barcelona for a concert. She has the picture, the key, the name of the street. And nothing to lose.

“If they had told me that it was a global bestseller, I would have believed it. It’s been a while since I’ve found anything like it and I still cannot believe it found its way to me.”
