Vienna, 1899. Josef Breuer - celebrated psychoanalyst - is about to encounter his strangest case yet. Found by the lunatic asylum, thin, head shaved, she claims to have no name - to be, in fact, not even human. Intrigued, Breuer determines to fathom the roots of her disturbance.

Years later, in Germany, we meet Krysta. Krysta's Papa is busy working in the infirmary with the 'animal people', so little Krysta plays alone, lost in the stories of Hansel and Gretel, the Pied Piper, and more. And then the real world becomes as frightening as any fairy tale . . .
