On the African continent, in the picturesque savannah, the noble and just ruler Mufasa, who is the head of the lion pride, rules. One day, a son was born to the king, who will continue his father's work. Animals sincerely rejoice at the birth of Simba's heir, and only the monarch's own brother, Scar, who has long dreamed of taking the place of a relative, was not happy about the birth of his nephew, since now he is the main contender for the throne. The insidious uncle begins to build a cunning plan to get rid of the baby and Mufasa at the same time.

Having arranged an accident during the migration of a herd of wildebeest, Scar created a death trap for an unsuspecting leader. The death of a parent greatly affected the little lion cub, who, by order of his uncle, having survived a terrible betrayal, went into forced exile. Filled with dangers for the young but brave Simba, the journey ends with meeting new friends. Extravagant friends who cannot imagine their own life without adventures help him cope with problems. Growing up, the main character gains confidence in his abilities, as well as the determination to restore justice.
