Based on the best seller of Margaret Mazzantini. It is 2008. Filled with memories of the four-year siege of Sarajevo, Gemma anxiously boards a flight from her native Rome to that war-scarred city with her son, Pietro. Sixteen years ago, in the thick of the conflict, Pietro was born. That night Gemma fled on a Red Cross cargo plane back to Rome with her newborn son, just hours old. Left behind were her husband Diego, whom she would not see alive again, and the makeshift family of siege survivors they had come to love. With this trip, Gemma now hopes to teach her son about the city of his birth and about Diego, the father he never knew. Locked away within her is the secret guilt that Pietro’s birth — a mysterious event in its own ways — started the chain of events that would lead to Diego’s death.
