In a desperate bid to escape the clutches of the Black Magic cult of Ubasti, Princess Nadji, believed to be the reincarnation of their goddess Ossana, takes refuge with Frank Chandler, a powerful White Magician, in California. However, the cult's high priest Vindhyan eventually puts Nadji under a trance, prompting Chandu to move her to the South Seas to prevent her sacrifice.
The Return of Chandu
The cult of Ubasti, based on the mystical isle of Lemuria, mistakenly believes Princess Nadji of Egypt is a reincarnation of their ancient goddess Ossana, and plans to sacrifice her to revive Ossana from the dead.
