Filmmaker Royce Osborn uses vintage stills and clips and interviews with Carnival veterans to explore the stamp New Orleans blacks have put on Mardi Gras. The hour begins in Congo Square in slavery days. The slaves' only allies: Native Americans. Today, blacks honor the alliance with Carnival costumes incorporating elaborate Indian headdresses. Osborn also traces the history of the Zulu Social Aid and Pleasure Club. "Zulu was politically incorrect," he says, "long before that term was invented."
