A doctor calls on Tarzan to topple the native witch doctor whose black magic remedies are killing patients.

Dr. Sturdy is trying to establish a modern hospital in the jungle. His efforts are strongly opposed by Futa, the witch doctor, and Ramo, a native warrior. There are kidnappings, a race against time for serum, capture of Tarzan, the struggle of modern medicine against magic, etc.—Ed Stephan <[email protected]>

Tarzan welcomes back Dr. Ken Warwick whose been away studying medicine for two years. There's trouble brewing however when the local witch doctor, Futa, sees his influence with the villagers waning in favor of the local clinic run by Dr. Sturdy and Dr. Warwick. The tribal chief has died and when his son and heir falls ill, Futa decides he is the one who has to treat him. Futa's henchman, Ramo, steals what he thinks is medicine but is actually a deadly serum. If given to the boy-chief, he will surely die. It's left to Tarzan to try and avert tragedy.—garykmcd

Using intimidation, superstition, and false prophecies, the evil witch-doctor, Futa, terrorises the peaceful neighbouring tribe of the Nagasu to usurp the throne. Now, as Futa turns his followers against Dr Sturdy and Dr Warwick, the white doctors of the local hospital, Tarzan decides to take matters into his own hands and thwart the ruthless magician's plans. However, with Jane's life hanging by a thread, and the Nagasu chieftain gravely ill, things take a dangerous turn. Indeed, this life-or-death situation calls for immediate action; however, Tarzan, too, is fighting for his life. Will Tarzan, the powerful lord of the jungle, spend the rest of his life in captivity?—Nick Riganas
