Tarzan [John Clayton]; Jane Porter Clayton; Boy [Jack Clayton]; Dombie; Jad-Bal-Ja; Loalla; Chief Kisumu; Witch Doctor Kururi
Chief Muviro's grandson, Dombie, has run away from home. Boy, the son of Tarzan, traces the boy to a village led by Chief Kisumu, who in turn is controlled by witch doctor Kururi. They both deny any involvement, but they are secretly holding Dombie, planning to sell him to Muviro's enemies. Kururi tries to scare Boy off with tales of the ghost of Makuru, who haunts the village at night in the form of a lion. But Boy does not scare so easily. The witch doctor attracts a lion with some goat's blood, but Tarzan's tame lion Jad-Bal-Ja chases the wild lion off. Tarzan and his son free Dombie.
