Following his acclaimed series, 'Into Africa' (also produced by Wall to Wall for PBS/BBC), Henry Louis Gates Jr. – Harvard's chair of Afro-American Studies – now travels the length and breadth of the United States to take the temperature of black America at the start of the 21st century.

In four films, Gates travels across the US to meet the people who are defining black America, from the most famous and influential – Colin Powell, Jesse Jackson, Russell Simmons, Stevie Wonder, Chris Tucker, Alicia Keys, Maya Angelou, Morgan Freeman, Samuel L. Jackson – to those at the grassroots.
