No witnesses.

Twelve-year-old Josy has an inexplicable illness. She vanishes without a trace from her doctor’s office during treatment. Four years later, Josy’s father, psychiatrist Viktor Larenz, has withdrawn himself to an isolated North Sea island in order to deal with the tragedy.

No body.

Then he’s paid a surprise visit by a beautiful stranger. Anna Glass is a novelist who suffers from an unusual form of schizophrenia: all the characters she creates for her books become real to her. In her last novel she has written about a young girl with an unknown illness who has disappeared without a trace.

Where is his daughter?

Can Anna’s delusions describe Josy’s last days? Reluctantly, Viktor agrees to take on her therapy in a final attempt to uncover the truth behind his daughter’s disappearance. But very soon these sessions take a dramatic turn as the past is dragged back into the light – with terrifying consequences.
