An auteur, together with his lead actors, is at a prestigious European festival to premiere his latest film. Alone one morning at a backstreet cafe, he strikes up a conversation with a local woman who takes him on a walk to uncover the city's secrets, historic and personal. As the walk unwinds, a story of love and tragedy emerges, and he begins to see the chance meeting as fate. He is entranced, wholly clear in his mind: her story must surely form the basis for his next film.
