In the Dominican Republic, Professor Gates explores how race has been socially constructed in a society whose people reflect centuries of inter-marriage, and how the country’s troubled history with Haiti informs notions about racial classification. In Haiti, Professor Gates tells the story of the birth of the first-ever black republic, and finds out how the slaves’s hard fight for liberation over Napoleon Bonaparte’s French Empire became a double-edged sword.

In Cuba, Professor Gates finds out how the culture, religion, politics and music of this island are inextricably linked to the huge amount of slave labor imported to produce its enormously profitable 19th-century sugar industry, and how race and racism have fared since Fidel Castro's Communist revolution in 1959. A Spanish SAP track for Black in Latin America will be available on the broadcast version and on the home video. (Part 2 of 4)

In Brazil, Harvard University professor Henry Louis Gates, Jr. delves behind the facade of Carnival to discover how this 'rainbow nation' is waking up to its legacy as the world's largest slave economy. A Spanish SAP track for Black in Latin America will be available on the broadcast version and on the home video. (Part 3 of 4)

In Mexico and Peru, Professor Gates explores the almost unknown history of the significant numbers of black people -- the two countries together received far more slaves than did the United States -- brought to these countries as early as the 16th and 17th centuries, and the worlds of culture that their descendants have created in Vera Cruz on the Gulf of Mexico, the Costa Chica region on the Pacific, and in and around Lima, Peru. A Spanish SAP track for Black in Latin America will be available on the broadcast version and on the home video. (Part 4 of 4)
