The Monkey King Sun Wukong lives a joyful life on Flower-Fruit Mountain along with his primate subjects. One day, Wukong accidentally breaks a sword while training with his companions. To find a more suitable weapon for himself, Wukong travels to the Dragon King's palace, where he obtains a powerful staff. Angered by Wukong's casual theft of his most precious treasure, the Dragon King goes to the Jade Emperor's palace in Heaven to demand retribution. The Jade Emperor hatches a plan to control the devilish monkey—however, Wukong may not be as easy to fool as the monarch thinks.
