When Professor Preston King stood up against the racist laws of segregation in America's Deep South, he had little idea his protest would result in an exile of 40 years. Now able to return, King travels to his home town of Albany in Georgia for a long-awaited reunion. He talks to black and white, old and young, and explores the legacy of racial segregation and its profound effects on his own life. Producer Linda Pressly. EMAIL: scirad@bbc.co.uk
