Winter 1943. Martina is a small child living in central Italy, who stopped talking since the death of her infant brother some years before. Her mother is pregnant again and Martina lives for the arrival of her new brother. Meanwhile, war is getting closer, and on almost the same day as the birth of her brother, the SS starts a massive roundup of civilians in the area, an infamous event that will come to be known as the Marzabotto massacre during which more than 770 people were killed.
