 It should not be confused with the 1943 film "Tarzan Triumphs", as the plots are not related.Real-life Soviet dictator Joseph Stalin is used as a minor character in the novel, though he remains in Moscow and does not personally take part in the action.Backed by Chief Muviro and his faithful Waziri warriors, Tarzan faces Soviet agents seeking revenge and a lost tribe descended from early Christians practicing a bizarre and debased religious cult.
