Winter, 1943. Eight-year-old Martina is the only child of a poor farming family and lives on the slopes of Monte Sole. Ever since her little brother died when just a few days old, Martina stopped talking. Her mother becomes pregnant again, while the war slowly draws nearer and the Nazis advance. The baby is finally born on the night between September 28 and 29, 1944. Almost at the same time the S.S. carry out an unprecedented round-up in the area, which will go down in history as the Marzabotto massacre.
