Donald Graham, imprisoned for a crime that actually was committed by John Cabin Branch, the man who stole Donald's acquisitive wife Corinne, joins a southern surveying team upon his release and becomes known as "the grouch." Following his dismissal, he works in a clubhouse situated on the edge of Okefenokee Swamp, and there he meets Fleurette, who has escaped from a band of pirates. Donald, who has become soured and misanthropic through his misfortune, treats Fleurette gruffly at first but finally softens towards her, marries her and takes her to the city. Upon learning that he has inherited a fortune, Donald uses the money to ruin Branch on the stock market, whereupon Corinne offers to return to him. Fleurette sets fire to Branch's house, but Donald arrives in time to save them both. Cured of his desire for revenge, Donald begins a new life with his beloved Fleurette.—AFI
