Standing among her white classmates, who stare straight into the camera, she enigmatically glances to the side.
Curiosity about the photograph - who the girl was and what she was doing in Germany - set the award-winning film-maker off on a path that led to Where Hands Touch, a new movie starring Amandla Stenberg and George MacKay.
