This is definitely my favorite Disney movie. The plot is set in Africa in the Pride Lands, where a Lion named Mufasa is the king of the jungle. He have a son named Simba with his wife Sarabi. Simba have always been with his best friend Nala and protected by Mufasa's hornbill majordomo Zazu. When Simba grow up will be the king of the Pride Rock. This is seen with envy by Scar, Mufasa's brother. Scar killed Mufasa in a stampede produced by the hyenas who received Scar orders. In the stampede Mufasa saved Simba and Scar took advantage of this and told Simba that was his fault; thus, Simba left the Pride Lands.

Scar thought that the hyenas killed Simba, so he announced the death of Mufasa and Simba to take control of the Pride Lands. Still, Simba did not die and lived his whole life with a meerkat and a warthog named Timon and Pumba respectively, under the motto "hakuna matata" ("no worries"). Once they found with a lioness who turned out to be Nala. She asked Simba to return home because the Pride Lands were devastated under the command of Scar. He refused at first, but after finding with Mufasa's mandrill friend and advisor Rafiki, he saw his father's ghost and decided to return home. 

Finally, Simba arrived home with Timon, Pumba and Nala. In the Pride Rock they found Zazu, who helped them to fight against Scar and the hyenas. After a surprised arrival of Simba, Scar noticed that the hyenas didn't kill him and acted with sarcasm towards Simba. Suddenly, a fight between Simba and his uncle developed in the Pride Rock. Scar lost the fight and fell off the cliff, but he died because the hyenas ate him not because of the fall. The circle of life continues when Rafiki presents Simba and Nala's newborn cub to the inhabitants of the Pride Lands.
