Southern Justice portrays the grisly treatment of the Negroes and their white supporter in the South after the Civil War or, as the Southerns would say, the "War Between the States." The story takes place in Louisiana during the period of 1871-1874. The two main characters, Charles Dubonet and Benjamin Bodine, are both plantation owner with extremely different characters profiles. Dubonet, the proprietor of "Oakwood" plantation, is a kind, sensitive Frenchman who treats his family, friends and plantation workers with care and respect. While Bodine, the owner of the "Whitehurst" plantation, is a hard-drinking, sadistic leader of a group of white-robed and hooded men who call themselves "The Knights of the White Kamillia."

Following many exciting twists and turns, Dubonet, with the aid of workers, friends and voodoo rituals, finds a way to end the torture, rape and murder of Bodine's bloody carnage.
