Frank Yerby's Foxes of Harrow was one of those long historical novels so popular in the 1940s. 20th Century-Fox boiled the novel down into 118 minutes' worth of essentials for this film version. In antebellum New Orleans, roguish Irish gambler Rex Harrison buys his way into society--something he couldn't do in his homeland because he is illegitimate. Sequestering himself in a mansion won in a card game, Harrison courts Southern belle Maureen O'Hara, but their subsequent marriage is befouled by Rex's incessant womanizing. Though tempted to walk out for good, O'Hara stays by her husband's side after he loses his fortune, hoping that the impoverished Harrison will now behave more responsibly.
