Ryan is an adolescent lion cub who wants to be able to roar like his father Samson. All he can apparently do is make a squeaky growling noise. He likes hearing Samson's stories about the wild, although none of them were true. One day, Ryan inadvertently provokes a gazelle stampede, which invokes Samson's anger over losing the turtle curling championship. After Samson scolds Ryan and lectures him about not being able to roar, Ryan sneaks into a green transport box and winds up getting shipped to Africa. After reuniting with his father and learning the truth about where Samson came from, Ryan eventually finds his inner roar (which he uses to defeat Kazar) and heads back home with his father and the other animals.
