Simone Segre, a renowned surgeon of Jewish origins, lives in a city northeast of Italy. A quiet life, an elegant apartment, and no connection with his past. One day he finds himself assisting a man victim of a hit-and-run accident. But when he discovers a nazi tattoo on his chest, Simone abandons him to his destiny. Filled with guilt, he traces the man’s family: Marica, the eldest daughter; Marcello, a teenager plagued with racial hate; and little Paolo. The night will come when Marica knocks at Simone’s door and unknowingly asks for payback.
