Archival footage and interviews with those who knew her well chronicle the extraordinary life of Fannie Lou Hamer. She attended the 1964 Democratic National Convention as a member of the Mississippi Freedom Democratic Party, challenging the all-white official Mississippi delegation, and many credit her presence as the impetus for the passage of the 1965 Voting Rights Act. U.S. Rep. Eleanor Holmes Norton (D-DC); Dorothy Height, president of the National Council of Negro Women; Rutgers University history professor Clement Price; and numerous members of the Mississippi Freedom Democratic Party talk about Hamer and her legacy. Sweet Honey in the Rock founder Bernice Johnson Reagon narrates.
