From a big rock on Flower Fruit Mountain, a monkey named Sun Wukong jumps out. He learns many skills and magical powers during his travels. When he returns home, he borrows a powerful item from the Dragon King and causes trouble in the underworld by messing with the Book of Life and Death.

The Dragon King and the King of Hell tell the Jade Emperor in Heaven about him. Sun Wukong is summoned and given a lowly job as a stable keeper. Feeling insulted, he goes back to Flower Fruit Mountain and calls himself the “Great Sage Equal to Heaven.”

The Jade Emperor sends troops to capture him, but Sun Wukong defeats them and escapes to Earth. After causing chaos at a peach banquet, he runs away again. Heaven attacks Flower Fruit Mountain once more, and this time, Sun Wukong is captured and put in a furnace to be turned into pills. Surprisingly, he survives and gains new powers called Fiery Eyes and Golden Vision.

After escaping from the furnace, he rebels against Heaven again. Finally, the Buddha steps in, trapping him under a mountain and promising that someone will free him many years later.
