While her minions lure the three demons into the forest, the demoness tells Sanzang a story about how she was forced to marry as a young girl, and when her village suffered with famine, the people blamed her for it, even calling her an evil demon, and wanted to sacrifice her to the gods.
As Sanzang comforts the old lady, she attempts to kill him, but is stopped by Wukong who had seen through her disguise with his Fiery Eyes. Sanzang and the others don't believe Wukong that all the women he murdered were demons, and blame him for killing the innocent.
The group arrives to the kingdom's capital and the King (Fei Xiang) throws a feast for them, begging Sanzang to exorcise the bloodthirsty demoness.
On his travels he accidentally frees Wukong and the Monkey King learns from the Mercy Goddess (Kelly Chen) that he has to protect the monk throughout the journey.
They also meet Zhu Baije (Xiaoshenyang), a lustful pig demon, and Sha Wujing (Him Law), a djinn-like monk. The company travel to the Yun Hai Xi Kingdom, a land terrorized by the White Bone Demon (Gong Li) who snatches children.
As the demoness learns about Sanzang, she decides to eat him in order to stop her reincarnation cycle and achieve everlasting demon-hood.
She transforms into an old woman and beguiles the group into her cottage in the woods.
She tries to persuade Wukong to let her eat the monk, but he deceives her instead, and a fight ensues.
During the chaos, the King's guards kidnap Sanzang, but before the King kills him in order to cure himself of a disease - as he has been actually kidnapping all the children and blaming the White Bone Demon - Wukong saves him and the children as well.
All of the group are celebrated as heroes, but as a little girl approaches Sanzang, Wukong kills her and her mother as well, seeing the demoness possessing them.
