Scar plots to kill Simba and Mufasa, and leads them to a gorge. There Mufasa is killed by a herd of Wildebeest, and Simba is led to believe by Scar that he is responsible for his death. Simba then runs away, and Scar becomes king of the pridelands. After several years, in which time Simba has grown up, he returns with the help of some new friends to the pridelands, where Simba has a final battle with Scar and wins back the pridelands.
