Mischievous King Monkey is summoned to Heaven, where he steals the heavenly peaches, and eats them to gain immortality. He fights two of the Emperor's officials, and all three of them are expelled to Earth. Monkey gets imprisoned under a mountain of rocks, while the other two are transformed into a pig monster (Pigsy) and a water monster (Sandy). Buddha says that a holy man must be sent to fetch holy scriptures from India, to save the world.

Tripitaka and the ever-impatient Monkey begin their perilous journey. Arriving at a village terrorised by a greedy and lustful monster, Monkey thus faces the wrath of Pigsy and his deadly muckrake.

When the pilgrims later discover that Monkey was telling the truth, Tripitaka finds himself in grave danger, and wishes he'd never denied the demons' existence.

Desperate for water due to the intense heat, the pilgrims find that the nearest village is completely dried up.

When Monkey saves a pretty widow from the Demon Spirit of Great Snakes, amorous Pigsy falls snout over trotters in love with her, but she only has eyes for the celibate boy priest Tripitaka.

When Monkey goes to fetch Pigsy, Tripitaka and eel-phobic Sandy end up in big trouble.

When the magistrate Lord Li's stepdaughter is kidnapped by bandits, Monkey reluctantly takes on the job of catching them.

The blood-sucking Queen of Night terrorises the inhabitants of her land, while everyone in the land of day is forced into slavery by their merciless king.

A village headman and his wife grieve for their beautiful daughter Hai-Min who disappeared a year ago. Lecherous Pigsy offers to go and look for her.

How long will it be before she discovers he's not her slimy husband?

The pilgrims enter a volcanic land that is plagued by earthquakes caused by the frequent quarrelling of two local demons; a catfish demon and a faceless shape-changer demon, who can take on the shape of anyone.

While climbing a mountain, the pilgrims discover a man who's been digging a tunnel through the mountain for the past twenty-two years, to provide an easier route for travellers.

While Monkey struggles to resist the king's magic ring, Pigsy finds it difficult to resist Chun-Shou.

Following a terrible sandstorm, the pilgrims find a village where everyone has been killed by the evil Grey Gloves Devil, a magician with the power to hypnotise and control anyone who looks into his eyes.

In a deserted village, the evil male demon Wun-Lung and three beautiful witches await the arrival of Tripitaka, Monkey, Pigsy and Sandy.

Who'll be the first pilgrim to fall into the trap?

Forty years before the pilgrims' journey to India, two lovers Chun-Ying and Yu-Lee disobey the God of Fertility Ju-Lee by eloping together - love is forbidden in his country. As punishment, he separates them and turns the young Yu-Lee into an old woman, the Keeper of the Well of Small Blessings.
