The Exorcist's Meter

Taxi driver LUK KA-YAT has a strange encounter at midnight after giving a ride to a woman in red, so his taxi driver friend MA KWAI starts telling other fellow cab drivers as to what happened. Among them, WONG SIU-DAN, who is armed with all sorts of spells, charms and malas, warns KA-YAT that his taxi is haunted. Instantly, MA KWAI and his non-blood related uncle MOK YAU-WAI stop SIU-DAN from continuing because they do not believe in ghosts. MA KWAI learns that his crush, female doctor CHONG TSZ-YEUK, calls a taxi, so he rushes there only to run into all sorts of obstacles along the way. Just as he is about to urinate, he receives a call from a customer. The senior arrives yet soon disappears, leaving MA KWAI no other choice but to go into the bushes to urinate in a hurry. After he returns home, his mother LEUNG CHING-CHING, a devoted Buddhist, mentions that she wants to buy a Dzi bead worth $100,000 so as to keep her home and family safe, to which MA KWAI refuses. Following the ensuing dispute, MA KWAI goes upstairs to MOK YAU-WAI’s home to complain about this. There is a burst of gunfire at Hung Hom, so all the cab drives spread the message warning the others not to go there. Out of the blue, MA KWAI’s mobile phone breaks. He ends up being taken hostage by the armed criminal. While exchanging gunfire with the criminal, police officer KWOK CHIN-MING notices that his eyes are all re

In his dream, MA KWAI vaguely sees a muddy man. After that, he notices there is some mud on his face. Despite the extensive news coverage of his story, MA KWAI seems to be very unhappy. MA KWAI’s $100,000 that he planned to give to his mother is taken by the police as evidence, so he can’t buy the Dzi bead anymore. The police officer who was patrolling together with CHIN-MING during the gunfire exchange is fatally injured. Later, CHIN-MING tells his younger sister PUI-LING that he was killed in the line of duty. After the police take the statement from CHIN-MING, they find it too inconceivable. While CHIN-MING is so gloomy at the hospital, he runs into his old neighbor TSZ-YEUK, and the two even make an appointment to have lunch together. Seeing the paranormal phenomena from her TV, CHING-CHING becomes so scared that she goes to YAU-WAI’s home and asks for help. Meanwhile, MA KWAI tries every possible way to finally get the opportunity to drive TSZ-YEUK home. TSZ-YEUK even asks him for his mobile phone so as to directly call him for a taxi. CHING-CHING asks SIU-DAN to find her an exorcist to cast out the ghost, causing a disturbance…

A mysterious creature appears in front of MA KWAI, and soon turns into a humanoid form after shaking the mud off its body. The creature explains to MA KWAI that as an incarnation of heavenly virtues, he is a genie of the rock who has been sleeping for three hundred years and is now coincidentally woken by MA KWAI, adding that his name is SHEK KAM-DONG. Not wanting KAM-DONG to follow him, MA KWAI starts speaking to him in an abusive way. However, KAM-DONG frankly tells MA KWAI that he is going to grant him a wish to repay a debt of gratitude. When CHIN-MING is on patrol, a concerned citizen complains to him that there is an unpleasant smell coming from KA-YAT’s taxi with a sight of blood. After he returns to the police station, PUI-LING reveals that she was told by the police that her elder brother’s death stemmed from the negligence on duty, and she begs CHIN-MING to help her probe into the matter. As usual, MA KWAI drives TSZ-YEUK back home after she gets off work. Driving by the seashore near Sai Wan, TEUK out of the blue starts telling him about things happened between her and her boyfriend. YAU-WAI helps CHING-CHING cleanup so as to prevent rodents, during which he discovers a box containing some children’s stuff.

MA KWAI eventually thinks of what kind of wish he wants to fulfill, so he tries to contact KAM-DONG, but to no avail. Due to the upcoming demolition of her old residence, TSZ-YEUK invites CHIN-MING to tour around the old neighborhood together with her. Feeling anguished by his experience, CHIN-MING reveals to her that there has been many falling from height incidents at the Shing Pak Building ever since she moved out. All the fellow cab drivers are gossiping about the haunted stories at the TV station. Seeing that MA KWAI also agrees with them, YAU-WAI can’t help feeling very disappointed and leaves. Finally, MA KWAI manages to locate the rock that KAM-DONG is attached to, and he even hears his calling for help. MASTER YAT-KI live broadcasts the program, Big Big World. In order to achieve the highest clickthrough rate, the producer even tells the host PUI PUI-NA to stand in a protective barrier filled with joss paper, spells, charms and other paper offerings. It’s widely spread among the fellow cab driverat there are paranormal phenomena around the electricity transmitter near the TV station. Having heard this, MA KWAI rushes there…

MA KWAI carries the sacred rock back home and plans to hide it in his room, however, KAM-DONG is not satisfied because his room is as messy as a dumpster. Seeing MA KWAI act very weird, CHING-CHING comes up with an idea to divert MA KWAI’s attention away. MA KWAI later returns to his room only to find out that the sacred rock has gone missing. PUI-LING asks CHIN-MING whether there is any progress regarding her brother being accused of negligence, to which CHIN-MING eventually can’t hold on anymore and tells her that he also saw the red-eyed demon. KAM-DONG follows MA KWAI to work to not only avoid running into trouble but also to learn modern technology. When TSZ-YEUK gets off work, she confides in MA KWAI. Seeing TSZ-YEUK exude elegance, KAM-DONG encourages MA KWAI to confess his love to her, his dream girl. Seeing that MA KWAI is a very filial son, KAM-DONG can’t help feeling puzzled about the fact that CHING-CHING still treats MA KWAI badly, so MA KWAI reveals the reason behind this. As requested by llow cab driver MAN BIU, MA KWAI picks up two “young friends” for him, only to find out that they are gang members. While patrolling, CHIN-MING sees MA KWAI, so he instantly goes to talk to hi

Though MA KWAI insists that he has nothing to do with the drugs, he is still detained by the police. CHIN-MING volunteers to talk to MA KWAI, seeking to find out more things about the red-eyed demon through him. MA KWAI reveals to YAU-WAI that he has been detained by the police, begging him not to disclose this to his mother, so YAU-WAI seeks aid from Uncle BIU but fails. Eventually, MA KWAI is released. However, upon his return, CHING-CHING instantly reprimands him for causing trouble. Feeling that he was wronged, MA KWAI loses his temper and runs away from home. While doing her rounds, TSZ-YEUK sees WING-SHING refusing to eat. TSZ-YEUK then buys some street snacks and visits WING-SHING, who reveals the reason why he is still alive is to see CHIN-MING. WING-SHING begs TSZ-YEUK to bring CHIN-MING there to visit him. In order to find the ghost of HO, MA KWAI leads KAM-DONG to the place where HO passed away. Due to the fact that KAM-DONG is unable to find HO’s ghost, he passes his Genie power to MA KWAI, helpg open his third eye.
