Simba, a young lion prince, flees his kingdom after the murder of his father, Mufasa. Years later, a chance encounter with Nala, a lioness, causes him to return and take back what is rightfully his.
Set during the days of the Pleistocene ice age, the film centers around three main characters—Manny, a no-nonsense woolly mammoth; Sid, a loudmouthed ground sloth; and Diego, a sardonic smilodon—who come across a human baby and work together to return it to its tribe.
