To make matters worse, his sister makes fun of his inability to "live in the jungle" without food. Now hungry and mad, Marty decides he will run away to show his family he can live in the wild. Under the light of a full moon, he makes a dash for the creek. Marty's father went for a walk down this very creek one year ago and never returned. The young hungry lion makes a brave decision to find out what really happened to his father. His adventure begins as he sets off on a quest for answers. Unlikely individuals form friendships while uncovering the truth about Marty's father. The search for answers quickly turns into a rescue mission that takes the new friends to the most breathtaking and treacherous land they have ever seen.
