Some 6.7 million people — more than a quarter of the global refugee population — have fled brutal violence in Syria, the report said. This documentary chronicles the stories of some of the youngest. Filmed over three years, it follows four Syrian children from their struggle to survive the siege of Aleppo by President Bashar al-Assad’s regime, to the devastating kidnapping of their father, to the beginning of their new lives as refugees. “These children, if we give them a future, they will benefit their homeland,” their mother, Hala Kamil, said in the film. “They will rebuild it.”
