In the jungles of India, an orphaned human infant named Mowgli is taken in by a wolf pack under the sponsorship of the black panther, Bagheera. As Mowgli grows up with his canine family, he finds that he has a lot to learn about life in the jungle under the tutelage of Bagheera and Baloo the Bear. At the same time, Mowgli learns to thrive in his own way as he handles the threat of the tiger, Shere Khan and his minions. Throughout the boy's adventures, there is also the growing mystery of his origins and humanity that would change his life forever.
Akela is always sick, and without his guidance the pack is in such disarray that it can’t even attack a herd of buffalo successfully. Shere Khan and Tabaqui take advantage of the situation, and attack the wolves' camp; even the monkeys start to make fun of Akela and his companions.
Mowgli and his friends discover that Grizzle is still in the forest, under the protection of Saga, an old wolf, who has enlisted the rogue wolf’s aid. Together, their plan is to usurp Akela’s power and steal his throne. When Luri becomes aware of the situation, she takes matters into her own hands and draws up a plan to defeat the enemy.
Before attacking the enemy, Grizzle’s hiding place must be made known. Mowgli and the others hunt for Grizzle, but without Chil’s help, they would have never discovered his ambuscade in the old, abandoned temple.
Mowgli and the others kill Grizzle but Luri explains to Mowgli that the pack cannot last without a leader and sends him to find Vermillion and bring him back.
Mowgli finds Vermillion and asks him to return to the pack and take Akela’s place, but the wolf refuses and advises that the boy propose Luri as leader. Akela agrees to relinquish his power, and so Luri becomes the new leader of the pack even though she is a female.
Bagheera has been injured. While out searching for medicinal plants with which to treat the panther, Mowgli runs into the man who saved him from the trap. This time he has a little girl called Jumeirah with him, who makes a deep impression on the boy.
Mowgli returns more and more frequently to the territories near the human settlement where his new friends live, and one day Shere Khan decides to follow him. Beautiful Jumeirah teaches the boy to talk, and the little "savage" is enthusiastic about his teacher and her lessons. Bagheera, Baloo and Kichi are concerned because they don’t understand what is happening to Mowgli. Meanwhile, Shere Khan has every intention of eating the boy and Jumeirah.
Mowgli and Shere Khan engage in mortal combat. The boy is about to be overcome when the old Rahar comes to the rescue and, in spite of receiving serious injuries, drives the tiger away, but not before Mowgli manages to slash the tiger's eye. Mowgli and Jumeirah carry the injured man home, and when Jumeirah’s mother, Meshua, sees Mowgli she is convinced he is her son, Keshnu, who was lost in the jungle and never seen again. Her husband and daughter try to calm the woman down, explaining that Mowgli cannot possibly be her son, but in any case, he has just saved grandfather Rahhar from the tiger's fangs.
Mowgli is very attracted by the lifestyle of his own kind and wants to stay with Jumeirah. Unfortunately, people are unkind to him: the village youths, a boy named Ganshum in particular, make fun of the little savage, and the elders want to sell him to a circus. However, in spite of everything, Mowgli bids his animal friends farewell, determined to stay with Jumeirah.
Buldeo, the evil hunter of the village, and Ganshum’s grandfather, tells his outraged fellow villagers an incredible story: one day, he ventured deep into the jungle and came upon some grey monkeys guarding the secret of eternal youth, who offered him some delicious wine. But this was not all; Buldeo knows that the king of all the animals is a chimeric dragon, known as the "Fire Dragon". He tells his audience that Shere Khan is possessed by the soul of the village's most hated man, named Purun Dass, who died the year before and is then determined to take revenge by killing everyone in the village. As proof that the tiger is the reincarnation of the thief, Buldeo adds that they both have a scarred eye. It becomes quite clear that Mowgli will soon have another fight on his hands.
In order to avenge his wolf father, Alexander, Mowgli is determined to kill Shere Khan with a dagger and the help of his friends, but Chil reports that the tiger has disappeared. While Kaa sets out to track down Shere Khan, Sura and Akru remain at Mowgli’s side.
Akela’s plan of attack against Shere Khan calls on Mowgli to play a decisive role: the boy will be the one who engages the tiger in the final duel. After overcoming much peril, he is to succeed in this endeavor.
Mowgli is ordered by Buldeo to bring Shere Khan’s corpse into the village to prove that he has not been lying, and that if he cannot do this, then he will be severely punished. Mowgli accepts the challenge, and, with the help of the animals, a torch, and Rahhar’s knife, manages to subdue the tiger, ultimately killing his prey. However, the perfidious Buldeo plans to pocket the reward on the tiger’s head. In order to do this, he goes to great pains to prove to the villagers that in fact he is the one responsible for the death of the tiger, and that Mowgli is merely a conniving sorcerer. Mowgli turns his back on the village and returns to his friends in the jungle. Jumeirah is very sad to see him go.
Chil the eagle, warns the animals of the Seeonee forest that a terrible calamity awaits them: an invasion by the dholes, a pack of red dogs pushed northwards by thirst and hunger. After a long meeting at which Luri is appointed commander-in-chief, Mowgli’s mother decides to send the boy to fetch Kaa so that she can consult the snake about drawing up a defensive plan. Kaa comes up with a most ingenious idea.
The red dogs reach the forest of Seeonee where Mowgli is waiting for them. When the sun goes down, he puts Kaa’s plan into action, luring the dogs into Death Valley where a swarm of black bees attacks them. The surviving dogs throw themselves into the river and are carried by the current into the mouths of the wolves who have the chance to show off their fighting skills. The dangerous enemy has been defeated and peace returns to the forest of Seeonee.
The forest is celebrating the mating season. Mowgli and Bagheera feel left out because all the wolves have found partners. Bagheera’s stories about the mating season make Mowgli homesick for the beautiful Jumeirah. In the end, Mowgli runs to the village and discovers that Jumeirah and her family have been kidnapped. The door has been broken down and the house is empty.
A mongoose called Rikki-Tikki-Tavi tells Mowgli that after Buldeo vented his rage on Mowgli’s adopted family, that the villagers kidnapped Jumeirah and her parents, believing them to be demons. Mowgli runs to the village to help his friends, but along the way, he runs into Buldeo and Riswan who threaten to kill him.
Mowgli breaks into the hut where Rahhar and his family are held prisoner and sets them free, but they first ask him to provide them with food in order to build up their strength before they make their escape. While he is trying to hunt down Mowgli with a friend, Buldeo then encounters Bagheera.
With the help of the other animals, Mowgli makes it possible for Jumeirah and her family to escape, and, at the same time, manages to scare the villagers so badly that they do not attempt to even follow the fugitives. In order to avoid more problems, the animals then destroy the village and drive the humans out of the jungle.
Everyone is celebrating the birth of Sura and Lala's two cubs, but Mowgli feels homesick for Jumeirah, and decides to travel to Khanhiwara, where Jumeirah and her family went after they escaped from the villagers. But when he gets there, Mowgli comes face to face with Riswan, who seems to be nicer now. Or is he?
Mowgli is sold by Riswan to John J. Hargreaves, an intermediary who supplies animals for circuses. During the night, Mowgli manages to escape from the cage he is being held in.
Mowgli misses Jumeirah and thinks about her all the time, but he is distracted by the arrival of a herd of deer that is the perfect prey for hungry wolves.
Akela is seriously injured in a fight with a pack of hyenas, but instead of taking measures to heal himself, he refuses to eat and won’t accept any form of treatment because he feels his time has come. Shortly afterwards, he passes away as he had foreseen. Just before he dies, he advices Mowgli to go and live with the humans because "his heart won't allow him" to stay with the wolf pack.
After shedding his old skin, Kaa tells Mowgli about a curious habit of elephants, in which elephants from different jungles gather to dance together, and those who have the luck to see their dance are said to receive the gift of long life. Hathi allows Mowgli to bear witness to the elephant dance. Following this, the elephant gives Mowgli Jumeirah’s foulard, and immediately the boy wants to set out to join her, but he doesn’t know where she is. In the meantime, Jumeirah, Meshua, and Rahhar await Mowgli in the jungle after burying Sanjay, who had succumbed to pneumonia. However, as time passes, they gradually abandon any hope of seeing him again.
Mowgli is reunited with Jumeirah and her family after saving Jumeirah from some rambunctious monkeys, and together they decide to sow the fields again and become stock herders. However, some of the villagers appear, but Jumeirah's family forgives them for their past wrong-doings.
Mowgli decides to leave the jungle, but before going to live in the village with Jumeirah and her family, he bids farewell to all his animal friends, except Bagheera, who will accompany him. All the jungle animals then assemble at Council Rock to offer him a bittersweet good-bye. At the end of the episode, he is reunited with his old friends in the human village as he throws his Fang.
