PBS's premier international newsmagazine returns with three more "stories from a small planet," starting with the inside story of a group of shop owners and young activists who stood up to the powerful Sicilian mafia. In "Taking on the Mafia," FRONTLINE/World correspondent Carola Mamberto explores the story of a restaurant owner -- backed by an upstart anti-mafia movement of young people and an elite law enforcement team -- who refused to pay the mafia's monthly "tax," taking a stand against mob bosses who've kept Italy in their grip for decades. Also in this hour: the odyssey of several dozen men from their homes in rural China to years of detention in Guantanamo Bay, Cuba, and the story of a Brazilian politician who took the name "Barack Obama" for his historic bid to become the first black mayor of his town.
