After three death-defying adventures defeating world-class villains with his unmatched courage and mad martial arts skills, Po, the Dragon Warrior, is called upon by destiny to...give it a rest already. More specifically, he's tapped to become the Spiritual Leader of the Valley of Peace. That poses a couple of obvious problems. First, Po knows as much about spiritual leadership as he does about the paleo diet, and second, he needs to quickly find and train a new Dragon Warrior before he can assume his new lofty position.
