Young orphan boy Skeeter (Brandon deWilde) is being raised in a Mississippi swamp cabin by his poor and toothless Uncle Jesse Jackson (Walter Brennan). One night, a mysterious noise is heard. They later discover that the noise was caused by a strange breed of dog (My Lady of the Congo) they do not recognize. Rather than a bark, the dog has a yodel or laugh. The animal has keen senses, and they decide to train her for bird hunting.
