Yambo, a sixty-ish rare book dealer who lives in Milan has suffered a loss of memory; not the kind of memory neurologists call 'semantic' (Yambo remembers all about Julius Caesar and can recite every poem he has ever read), but rather his 'autobiographical' memory: he no longer knows his own name, doesn't recognize his wife or his daughters, doesn't remember anything about his parents or his childhood.
His wife, who is at his side as he slowly begins to recover, convinces him to return to his family home in the hills somewhere between Milan and Turin. Yambo promptly retreats to the sprawling attic, cluttered with boxes of newspapers, comics, records, photo albums and adolescent diaries. There, he relives the story of his generation: Mussolini, Catholic education and guilt, Josephine Baker, Flash Gordon, Cyrano de Bergerac. As he recovers his memory, two voids remain shrouded in fog: a terrible event he experienced during the resistance, and the vague image of a girl whom he loved at sixteen, then lost.
But a relapse occurs. Now in a coma, his memories run wild, and life racing before his eyes takes the form of a graphic novel. Yambo struggles through the frames to find at last the face of the girl he loves: she descends the stairs of their high school and morphs into a Dante-esque promise (or threat) of the afterlife, as he struggles harder to capture her simple, innocent, real-life image - the schoolgirl he never forgot.
