A stirring profile of the great Sam Cooke (1931-64), who helped invent and popularize soul music with such classics as "You Send Me" (1957), "Chain Gang" (1960) and "A Change Is Gonna Come" (1962). It features a wealth of archival footage, including an insightful "American Bandstand" interview and Cooke's swinging rendition of Bob Dylan's "Blowin' in the Wind," as well as remarks from James Brown, Mel Carter, Sam Moore, Billy Preston, Lou Rawls and Smokey Robinson.
