At home in Africa, Tarzan (Mike Henry) assists a photojournalist named Myrna (Aliza Gur) and her associate Ken (Ron Gans) in their search for Erik Brunik (Steve Bond), a thirteen-year-old boy lost in the jungle since he was seven years old. Tarzan is assisted by his friend Buhara (Ed Johnson) whose brother Nagambi (Rafer Johnson) does not wish the boy found, and attempts to kill him before Tarzan saves the day.
All three of Mike Henry's Tarzan films were completed before the first (Tarzan and the Valley of Gold) was released in 1966.
The roles of opposing brothers Nagambi and Buhara were played by real life brothers Rafer and Ed Johnson.
Mike Henry was attacked and his jaw bitten by the chimpanzee playing Cheeta during filming (named Dinky in the previous production, Tarzan and the Great River) and sued Sy Weintraub's Banner Productions.[3] Citing exhaustion and unsafe work conditions in the suit, he bowed out of the Tarzan television series (for which he had been signed to play the lead). The case was settled for an undisclosed sum. Ron Ely replaced him as Tarzan in the TV series.
If one does not count two later theatrical releases of episodes from the Ron Ely TV series, this film was the final release in the "mainstream" Tarzan film franchise that had begun in 1918. The next official made-for-theatrical release production featuring the character would be Tarzan, the Ape Man, an attempted reboot of the concept, in 1981.
