Simba is the son of the Lion King Mufasa and Queen Sarabi, Scar’s nephew. As a child, he was a restless and curious lion cub, because of which he often got into trouble. After the sudden death of his father (who blames himself), the lion cub was forced to leave his native kingdom. Outside the homeland of the lion cub, the meerkat Timon and the warthog Pumba were sheltered and raised, and side by side with them, the runaway young prince lives a carefree and easy life. As an adult, Simba meets the spirit of his deceased father, who convinced him of his true destiny. The prince who had matured and understood himself had to return and save the Pride Lands from final decline.
Now he is the king of the Pride Lands, the husband of Nala and the father of three children: the daughter of the heir to Kiara, the son of Kayon, the leader of the Lion Guard and the eldest son of Kopa.
The prince grows up in a cheerful, restless, occasionally arrogant lion cub. He wants to quickly become the king, because he believes that this title gives the right to do what you want and go anywhere. The mercenary and cruel uncle Shar, whom the nephew deprived of the right to take the coveted throne by the fact of his appearance, decides to take advantage of Simba’s curiosity and deliberately tells him about the elephant cemetery – the land located outside the kingdom of Mufasa and inhabited by hungry hyenas – the minions of Scar. Simba goes there with her friend Nala. There, they attack the lion cubs sent by Scar hyenas. Fortunately, Simbu and Nalu have time to save Mufasa in time on time.
The fact that Simba went to a forbidden place and in addition endangered Nalu very upset his father. After this incident, the father reprimands his son, says that you need to be brave only when necessary. Mufasa also speaks with Simba about the stars, saying that the great Kings of the past live there – their ancestors who follow life from heaven.
Once, Scar comes up with a sinister plan to kill Mufasa and Simba, which does not end well: a strong and strong Mufasa helps his son out by pulling him from under the feet of frightened antelopes and putting him on a safe ledge, and tries to escape himself, but Scar throws him off. The surviving Simba is in despair. He finds his father’s body in the canyon and mourns beside him. At this moment, Scar approaches him, who accuses the prince of the death of the king and forces him to flee the Pride Lands. When the frightened Simba flees, Scar orders the hyenas to catch him and kill him. However, they are behind the lion cub on the way, having decided that outside the kingdom he “will die”, and return back.
The runaway prince finds his refuge in the jungle, where he was sheltered by the warthog Pumba and the meerkat Timon. They help the lion cub forget about the difficulties and teach him the new motto “Akuna Matata”, which means “no worries”. Next to Timon and Pumbaa, Simba became an adult lion. He doesn’t tell his close friends about his past and tries not to remember him. He succeeds until Nala, a childhood friend, accidentally comes into the jungle. The lioness who escaped from the devastated Pride Lands tells the warthog and meerkat that if Simba is alive, then he is the rightful king, and persuades him to return and engage in a fight with Scar. However, the young lion refuses, remembering that he is allegedly guilty of the death of his father. In the process of talking about the past, Simba and Nala, between whom love has already broken out, quarrel. The frustrated prince flees in anger into the fields, where Rafiki unexpectedly finds him. The wise mandrill shaman evokes the spirit of Mufasa, who reproaches his son for having forgotten his place in the circle of life, and orders him to return to his homeland. Impressed by what happened and suddenly enlightened, Simba decides to return home and fight for the king’s rightful place.
Returning, Simba discovers the empty Pride Lands. The lions and hyenas living here suffer from hunger: herds of ungulates have long left the desert territory. King Scar is trying to blame Sarabi, Simba’s mother, for this. He is angry with her, but in the midst of a quarrel, Simba appears. He tells his uncle to leave the throne, but Scar does not intend to give up. The old usurper is forcing Simba to publicly admit guilty to the death of his father. During the feud, Scar takes Simba to the edge of the cliff and intends to push him down, as he once did with his brother. But before that, the false king decides to confess to his nephew in the murder of Mufasa. Enraged, Simba gains a second strength, frees himself from the trap and, holding his uncle by the throat, makes him tell the truth. Angry lionesses from the pride fight the hyenas, while Simba pursues Scar and drives him to the top of the Rock. The ruler, who finds himself in a hopeless situation, says that in fact, hyenas are to blame for everything, but Simba remains adamant. Nevertheless, he leaves the killer uncle alive and invites him to escape from the kingdom, but he provokes a fight between them – Simba throws Scar off the cliff to the hyenas who have not suffered betrayal.
