Plot
Sun and Aki, two beauty consultants from Hong Kong, accept an offer to work at their company's new branch in Shenzhen. Their initial excitement turns into horror when they learn that their boss had tricked them. Their accommodation is a cheap hotel room rather than a new house, while the new branch has only one staff, Yee. That night, Aki's boyfriend, Bud Gay, brings the three of them to a disco run by his friends, the Lai brothers. With help from the Lai brothers, Bud Gay and his cousin Bud Yan, they distribute flyers to attract customers to their branch.

One evening, a strange man called Mr Cheng shows up and requests their services for his wife. He wants them to go to his home because it is inconvenient for his wife to travel. Sun follows him home and promises to heal Mrs Cheng's face after accepting a large sum of money from them. She does not know that the Cheng couple and their housekeeper are actually ghosts. When she tries to stop after the first session, she gets possessed by Mrs Cheng's ghost, who forces her to return and fulfil her end of the bargain. Aki notices that Sun is behaving strangely and learns from Yee that Sun is possessed.

In the meantime, Bud Yan reveals to the Lai brothers that their disco has attracted a large number of ghost patrons because they have unknowingly opened their disco during the Hungry Ghost Festival. They seek help from Bud Gay's mother, ghostbuster Mrs Bud Lung, to "cleanse" the disco and save Sun from the Cheng couple.
