 The screenplay is adapted from a novel by Marjorie Kennin Rawlings, better known I think for her book The Yearling which has also been films. Gal Young  Un centers on a spinster woman who lives alone in the woods of north Florida until she is swept off her feet by an opportunistic bootlegger. He marries her for her place and her daddy s money and her cooking and cleaning, which she freely shares. Inevitably, he shows his true colors in a variety of ways. One day he brings home a very young woman with clear intentions of keeping her as a mistress (a gal young  un) in the older woman s house. Business takes him elsewhere and the two woman are left alone in the woods together to come to terms with their shared exploitedness. The older woman s slowburn and eventual retaliation are masterfully crafted.
