The book consists of two parts. Some of the stories tell of Mowgli, about his life in the jungle among wild animals. At the age of two, the little son of a lumberjack is lost in the jungle. Behind him, the lame tiger Sher-Khan is scampering and wants to make him his prey. The child crawls to the lair of wolves. Father and Mother wolves take him to their family and protect them from Sher-Khan. They call it Mowgli, which in translation means “frog”. On the advice of the wolf pack, the bear of Baloo, who teaches the cubs to the law of the jungle, and the black panther Bagheera, who pays the flock for not giving the baby away for the tearing of Sher Khan, are in favor of Mowgli being allowed to live among the wolves.
The mind and courage of Mowgli allow him to survive and grow stronger in the difficult conditions of life in the jungle. His friends and patrons are the bear Balu, Bagheera, the boa constrictor Kaa, the leader of the wolf pack of Akelo. In his life there are many adventures, he learns to speak the language of all the inhabitants of the jungle, and this saves his life more than once.
Once the monkeys of Bandar Logs take the boy to the Cold Lairs, a ruined Hindu city, built in the jungle a few centuries ago. While the monkeys are carrying it, moving along branches of trees, Mowgli asks the kite to follow where he is being taken, and to warn his friends. Bagheera, Balu and Kaa come to the boy’s rescue and rescue him from monkeys who play
Ten years after Mowgli’s arrival in the jungle, the pack leader Akelo becomes old and can no longer patronize his pet. Many wolves hate Mowgli because they can not stand his sight and feel his inexplicable superiority. Sher-Khan is waiting for the right moment to deal with Mowgli. Then, on Bagira’s advice, Mowgli brings fire from the village. On the Rock of the Council of the wolf pack, he demonstrates to his beasts his strength, singing the skin of Sher-Khan, stands in defense of Akelo.
After that he leaves the jungle and goes to the village, to the people. There, a woman named Messua takes him for her son, once taken by Sher-Khan, and gives him shelter in his house. Mowgli teaches the human language, adapts to the way of life of people, and then for a few months becomes a shepherd of a village herd of buffaloes. Once he learns from the wolves devoted to him that Sher-Khan, who went to another part of the jungle to heal his wounds, has returned. Then Mowgli lures a tiger into a trap and sends a buffalo herd to him from two sides. Sher-Khan perishes. The village hunter who knew about the death of a tiger wishes himself 100 rupees for catching Sher-Khan and wants to take his skin to the village. Mowgli does not allow him to do this. Then the hunter calls him a werewolf, and Messua and her husband are sorcerers. Mowgli with tiger skin is hidden in the jungle. His named parents are going to be burned. Mowgli returns, helps them escape and get to the settlement of the English, from whom they can ask for protection. Mowgli sends wild elephants, buffaloes, deer to the village, and they trample all fields, destroy houses, disperse flocks, so that the inhabitants are forced to leave their former habitat and seek refuge in some other place.
After the death of Sher-Khan and the destruction of the village, Mowgli returns to the jungle, and now he is living particularly well. All recognize the rights of the master and the master of the jungle. He grows a handsome, strong and intelligent young man.
When he reaches seventeen years, the habitat of wolves is attacked by wild red dog dales. Each of them is weaker than a wolf, but they attack hordes, they are hungry and kill all life on their way. Mowgli, along with Kaa, lures them into a trap consisting of a billion swarm of wild bees and a swift river. The trick helps him to deal with most of the uninvited guests. Then the wolf pack finishes the survivors and the most stubborn ones. Thus, Mowgli relieves the wolves of certain death or forced relocation.
Spring comes, and Mowgli is drawn to the people. He says goodbye to his friends and finally leaves where now lives Messua and her newly born child. Mowgli meets a girl, marries her and leads a way of life that is normal for a human being, but always keeps in memory the first years spent in the jungle, and the images of true friends.
