It was directed by William Witney and John English based on the novel Jungle Girl (1932) by Edgar Rice Burroughs.
Dr. John Meredith, ashamed at the crime spree of his evil twin brother, Bradley, travels with his daughter, Nyoka, to Africa.
Years later, Slick Latimer and Bradley Meredith arrive looking for a local diamond mine and team up with the disgruntled Shamba.
Like many Republic adaptations, the contract to use a character called the Jungle Girl meant that showings of the serial after a set date were banned.
To avoid paying Burroughs a second time for the rights, the sequel used only the original material created by Republic Pictures for Jungle Girl (such as the name Nyoka).
