Venice. 1704. In this city of glittering splendour, desperation and destitution are never far away. At the Ospedale della Pietà, abandoned orphan girls are posted every through a tiny gap in the wall every day. Inspired by the true story of Anna Maria della Pieta, a Venetian orphan and violin prodigy who studied under Antonio Vivaldi.

Eight-year-old Anna Maria is just one of the three hundred girls growing up within the Pietà's walls – but she already knows she is different. Obsessive and gifted, she is on a mission to become Venice’s greatest violinist and composer, and in her remarkable world of colour and sound, it seems like nothing with stop her.
