Nyoka Gordon (Kay Aldridge) leads an expedition into the most remote part of the Libyan desert in search of her father, Professor Henry Gordon (Robert Strange), who disappeared while seeking out the long-lost golden tablets of Hippocrates. The tablets, among other attributes, are reputed to contain the cures for any number of deadly diseases that still plague mankind. Nyoka and her father are the only two people in the world who can translate the papyrus giving directions to the hiding place of the tablets. Her allies in her search include: Dr. Larry Grayson (Clayton Moore), a young physician; Torrini (Tristram Coffin), an Italian adventurer; Professor Campbell (Forbes Murray), a colleague of her father's; and Red Davis (Billy Benedict), their driver. Opposing them is Vultura (Lorna Gray), the leader of a deadly desert cult, who regard the tablets as sacred and will do anything -- including committing murder -- to prevent their discovery and removal. Aided by her ally, Cassib (Charles B. Middleton), and the Taureg tribesmen, Vultura and her cultists lay all manner of deadly traps, involving everything from burning pits of fire and tunnels filled with hurricane-like winds to just plain getting crushed by the embrace of Vultura's trained gorilla, Satan (Emil Van Horn). Meanwhile, Nyoka and her expedition also face the danger of treachery from within. Nyoka must first secure the papyrus and avenge the murder of Major Reynolds in the opening chapter, and then get past the opposing Taureg tribesmen -- and little does she realize that the leader of the Tauregs is far closer to her than she ever could have guessed.
