An unknown man comes ashore at a remote beach on the New South Wales coast. He is taken into detention and sent, ultimately, to Darwin. His captors call him Thursday after the day upon which he was found. Thursday doesn’t speak, but instead paints an enigmatic mural on the wall of his donga in the detention centre. It is a city, a dream city, and when he finishes he says a single word: Isinglass.
