The Exorcist's Meter

CHIN-MING brings along the seeds of Salvia Americana to PUI-LING’s art studio and plants them in a pot. While TSZ-YEUK tells CHIN-MING that she lost the camera that her ex-boyfriend left to her, she also leaves a message to MA KWAI, asking him whether he found the camera. Seeing that she confides in MA KWAI, CHIN-MING feels so jealous that he starts telling her about how MA KWAI was arrested on a drug possession charge, which according to him, proves that MA KWAI is not what he appears to be. Patrolling at night, CHIN-MING conducts a search on a drug addict, but finds nothing. However, after he out of the blue hears what the drug addict is thinking, he manages to arrest him on reasonable grounds. PUI-NA continues to hire MA KWAI to drive her around, asking him to share with her all sorts of paranormal and ghost stories. On one occasion, MA KWAI sees a senior sit on a wheelchair right in front of a hospital, yet neither nurses nor PUI-NA can see the patient. At that moment, MA KWAI comes to realize that the nior is a ghost. PUI-NA wants MA KWAI to reach that senior. Surprisingly, when MA KWAI tries to approach it, the ghost of WING-SHING suddenly starts wielding a blade, and accidentally injures PUI-NA in the ensuing chaos.
