As a young human orphan being raised by a family of gorillas in an African jungle, Tarzan is worried that a fabled monster known as the "Zugor" will someday catch him. He is disappointed that he cannot run as fast as the other young apes in his family, and his attempts to prove himself keep resulting in chaos. When an accident leaves Tarzan's ape mother, Kala, thinking that Tarzan has died, he chooses to run away, believing it to be best for everyone.
Alone in the jungle, Tarzan gets chased by Sabor the leopard into Dark Mountain, a rocky place inhabited by two hulking, spoiled gorilla brothers, Kago and Uto, and their controlling, over-protective mother Mama Gunda. They fear the Zugor as much as Tarzan does, and when the booming call of the monster again echoes through the valley, the trio flee and Tarzan is able to escape Dark Mountain. He encounters a crotchety old gorilla who at first keeps him distant, but Tarzan discovers this gorilla is actually named Zugor and is pretending to be the monster. He uses hollow trees and the Dark Mountain's caves and tunnels as megaphones to amplify his voice and pretend to be a monster, scaring other jungle creatures away from his territory and food. Tarzan uses this discovery to blackmail Zugor into letting the boy stay with him. Thanks to Tarzan's cheerfulness and helpfulness, Zugor begins to warm up to him. Tarzan continues to try to figure out what he is along with Zugor, but they both promise not to tell anyone.
Meanwhile, Tarzan's two best friends, the young gorilla Terk and the young elephant Tantor, come looking for him, and Kala also finds out that Tarzan is alive, so she goes looking for him as well, but allows the baby gorillas to join her. Terk and Tantor encounter trouble in Dark Mountain in the form of Mama Gunda, Uto, and Kago, but they are able to escape. Terk and Tantor eventually reunite with Tarzan, and the three become best friends once again. They leave Dark Mountain, and Mama Gunda, Uto, and Kago follow them. Tarzan does not want to return home with them but he reveals that there is no monster. Mama Gunda, Uto, and Kago overhear their conversation and learn it was Zugor who was pretending to be the monster; he gets himself into trouble. Uto and Kago wreck Zugor's treehouse in retaliation for scaring them. Zugor accuses Tarzan for breaking his promise and runs away, refusing to help him face the brothers. Terk and Tantor run to go and warn Kerchak. Kala and the baby gorillas arrive near Dark Mountain and also encounter trouble with Mama Gunda, Uto and Kago. Zugor finally realizes what Tarzan is supposed to be: a "Tarzan", with his own special tricks that no one else can do in the jungle. Zugor returns to Tarzan and reconciles with him.
Tarzan is able to use tricks and traps to defeat Uto and Kago as Terk and Tantor try to save Kala and the baby gorillas from falling off a cliff; Tarzan saves Kala just in time. Zugor holds Mama Gunda hostage, but due to their connection and Zugor accidentally telling Mama Gunda that she has "beautiful eyes", they both fall in love. Uto and Kago return and are shocked to see them together. Tarzan tells Kala that she was right before and he is a part of her gorilla family.
Tarzan, Kala, Terk, Tantor and the baby gorillas return to the gorilla troop, where Kala gives Tarzan a hug and tells him how proud she is of him for rescuing her from the fall and from Uto and Kago. Mama Gunda punishes her sons for destroying Zugor's treehouse and tells them that there will not be any more fighting or wrecking things. Tarzan, Terk, and Tantor decide to play a monster game; Tarzan is now happy and proud of himself, as he now knows what he is supposed to be. Tarzan stands on a tree and lets out the typical Tarzan yell.

At the start of the film, Tarzan is afraid of the Zugor, a mythical monster said to live on Dark mountain. He also fears that his mother Kala would get hurt because of him.
Glenn Close as Kala, Tarzan's adoptive gorilla mother who loves her son more than anything. She is caring and patient unless provoked, or if her family is in danger.
Brenda Grate as Terk, Tarzan's mischievous, quick-witted and sardonic "cousin". Her full name is Terkina, but she actually goes by Terk.

Lance Henriksen as Kerchak, Kala's mate and the leader of the gorilla family in the jungle who holds a dislike on Tarzan because of his human appearance.
