Henry Louis Gates, Jr. delves into the genealogy and genetics of celebrity guests who are bound together by an intimate, sometimes hidden link, whether it be as old friends, through long-lost relatives, or even through a common ancestral past. The series combines history and science in a fascinating exploration of race, family, and identity in today's America. Tonight, Gates shows journalists Christiane Amanpour, Ann Curry and Lisa Ling that the stories within their own family trees are every bit as compelling as the news stories they have been covering for the world.
