An ancient killer cult lives...and many people die! Under the leadership of charismatic Bacuna (Rafer Johnson), the murderous tribe has resurfaced, pillaging Amazon River villages, kidnapping inhabitants and enslaving them at Bacuna's secret enclave. Can Tarzan stop this relentless reign of terror?

As in his previous Tarzan and the Valley of Gold, Mike Henry plays the role of a re-imagined Tarzan who is similar to a globe-trotting superspy and equally at ease in a suit or loincloth. Sidekick chimp Cheetah joins the adventure (filmed in scenic Brazil), as does a companion lion named Baron. Not to be missed is the mano-a-mano finale between ex-NFL linebacker Henry and Olympic decathlon champ Johnson. Savor this clash of titans!

A joint U.S.-Swiss production in the waning days of the 35-year-old Tarzan series, this film stars Mike Henry in the second of his three film appearances as the jungle king. The film is set in South America, where one of Tarzan's friends is murdered at Tarzan's favorite zoo. The culprits are the Leopard Men, a group of tribal humans dressed and behaving like jungle animals. They are headed by Chief Barcuna (Rafer Johnson). Tarzan recruits Captain Sam Bishop (Jan Murray) and some animal friends to help defeat Barcuna, who is planning on leading a revolt of his Leopard Men against peaceful tribal leaders.
