Sudan enters its referendum on southern secession as Africa's largest country, and a filmmaker sets out ahead of the vote to see whether the nation once billed as a model of Arab-African, Muslim-Christian coexistence can hold together. Traveling through the north for the first time, he finds open hospitality, including strangers who stop to help when his hired car breaks down, alongside a stubborn belief in coffee shops and on streets that unity can still be saved and the South will never actually leave. Al Jazeera's account pushes past that hope to trace how the country's divisions run deeper than a simple north-south line, following the separatist pressures building in Darfur and the Nuba Mountains as those regions watch the referendum for a template of their own. The film treats Sudan's fracture as a test case other African and Arab independence movements are studying closely, weighing whether their own paths run through ballots or through armed struggle. It closes with the vote itself still pending, its outcome unresolved.
