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 daddys 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 womans house. Business takes him elsewhere and the two woman are left alone in the woods together to come to terms with their shared exploitedness.
