Mozart's Vienna. A crucible for scientific experimentation and courtly intrigue, as Europe's finest minds vie for imperial favour.

In a colourful, chaotic private hospital that echoes with the shrieks of hysterical patients, Franz Anton Mesmer is developing a series of controversial cure-alls for body and mind.

When he is asked to help restore the sight of a blind musical prodigy favoured by the Empress herself, he senses that fame, and even immortality, is within his grasp. Mesmer knows that he will have to gain her trust if he is to open her eyes. But at what cost to her fragile talent? And will their intimacy result in scandal?
