AOnce Leonard realizes that, thanks to his backing, black musicians can now write their own tickets, he arranges to sell Chess Records. When Etta learns about the sale, she sings her final song to him, tears in her eyes. In the middle of the song, Leonard walks out. He goes to his office, packs up the photos on his wall. trashes the room, and leaves, tears in his eyes. As he is driving down the street, he suffers a fatal heart attack. When Muddy tells Etta that Leonard didn't leave a will, she reveals that Leonard gave her the deed to her house just that morning. "He loved me," she concludes. In the final scenes, Dixon and Muddy fly to London where their airplane is met by scores of reporters, and a red carpet is laid at their feet. In his final narration, Dixon explains how the royalties from his songs allowed him to buy a recording studio where they continued to support musicians, be they rhythm and blues, rock and roll, or hip-hop.
