"As night falls over Vienna, Franz Ritter, an insomniac musicologist, takes to his sickbed with an unspecified illness and spends a restless night drifting between dreams and memories, revisiting the important chapters of his life: his ongoing fascination with the Middle East and his numerous travels to Istanbul, Aleppo, Damascus, and Tehran, as well as the various writers, artists, musicians, academics, orientalists, and explorers who populate this vast dreamscape.
