Schofield travels to the Austrian capital and, en route, former racing driver Niki Lauda talks about his current preoccupation, his airline. He meets Dr Andreas Rett, pioneer of music therapy, who first identified the mental and physical disorder affecting girls, Rett Syndrome; and the unconventional architect Hundertwasser, whose buildings include features like rooftop forests and sloping floors. Schofield takes a Third Man tour of the sewers with the film's location manager; visits the home of the Sachertorte, the renowned chocolate cake once at the centre of a bitter legal feud; meets the proprietor of a pet-cremation service, and a controversial artist.
