Through harsh jungle terrain, Tarzan escorts a notorious killer, intending to turn him over to authorities at Kairobi. The Ape-Man is not alone. A motley array of stranded travelers, dependent on his strength, goes with him. Meanwhile, the killer's vengeful kin stalks the group, waiting for the right time to attack.

Gordon Scott, in his sixth and final grab of the vine, is indeed magnificent in Tarzan the Magnificent, a dynamic color movie that maintains the mature approach and large-scale production of Scott's prior Tarzan's Greatest Adventure. Highlights include the powerful climactic brawl that in a sense is Tarzan vs. Tarzan, because squaring off against Scott is the actor who would succeed him as Lord of the Apes - Jock Mahoney.

Gordon Scott's fifth and last appearance as Tarzan came in this 1960 installment of the long-running movie series featuring the adventures of the legendary ape man. Neither Jane nor son Boy appear in the film. Tarzan is hired to escort a hardened criminal, Coy Banton (Jock Mahoney), through the jungle so that he can be turned over to the police. Also in the party are a group of British visitors including Ames (Lionel Jeffries), whose wife Fay (Betta St. John) falls in love with the prisoner Banton. Tarzan must stop the jungle party from fighting amongst themselves. After this film, Mahoney replaced Scott as Tarzan in subsequent movies, while Scott made several Italian movies playing the role of Hercules.
