The sensitive swordsman Cho Yi-Hang is tired of his life. He is the unwilling successor to the Wu-Tang clan throne and the unsure commander of the clan's forces in a war against foreign tribes and an evil cult. One day, he meets the beautiful Lien, a killer for the evil cult who is equally unsatisfied with her situation, but their love angers both the Wu-Tang clan and the evil cult.

This sequel to "Pandora's Box" continues director Jeffrey Lau's adaptation of the Buddhism saga "Journey to the West". Stranded five centuries in the past, Joker Monkey King must battle a variety of monsters, seductive women and super-powered villains to save the dying Pak Jing-Jing.

When the Goddess of Happiness tosses the Longevity Monk and his disciples out of heaven (because the Monkey King tried to attain immortality), the Monkey King is reincarnated as the Joker. He now spends his time chasing two jealous women. When one of them is dying, the Joker goes back in time in an attempt to save her.
