My Better Half

CHING SUM works for a pharmaceutical company called Man Shui Tong. His younger brother, CHING YEE, works there too, and he is a manager. SUM and YEE go to a commercial shooting with their boss LO CHUNG-CHUN. When they finish, SUM takes the models to one of the company’s retail shops to get some souvenir. Meanwhile, his wife, KO LAI-SUM, calls. LAI-SUM is an overbearing woman. He lies about where he is, and then LAI-SUM appears right in front of his eyes! LAI-SUM’s mother, KAM NGAN-FA, used to be the leader of a triad. The mother and daughter run a transportation company called Dragon Logistic Transport Co. They have four staff, who are better known as the FOUR KINGS. FA and the FOUR KINGS defend SUM. SUM wants to answer LAI-SUM’s call, but his mates, who are also his junior team members, KWONG SUN-SO and HUNG TSEUK-SHEK, do not let him. So LAI-SUM goes to SUM’s company instead……

LAI-SUM is requested to look at a lineup at the police station. She recognizes the sicko, who turns out to be SUM. She throws her cell phone at him, but hits Chief Inspector CHAN WING-YAN instead. The couple are detained. FA bails LAI-SUM out. She has an argument with LAM BAT-HANG, SUM’s mother, when she hears HANG only wants to release SUM. Meanwhile, YEE has come. He takes them all to dinner. During the meal, FA asks SUM to make it up to LAI-SUM. HANG tries hard to support her son, too. SUM is put into a very awkward situation. CHUN plans to fight for the dealership of the ZFM’s masks, a product by a prestigious cosmetic brand. He asks SUM to give some samples to the staff. SHEK and SO try every way to get some. LAI-SUM is not happy that SUM has not reserved any for her. YEE bumps into MIU LING-CHI, who has just broken up with her boyfriend. He asks her to have a one-night stand with him but she leaves mid-way……

YEE has employed CHI as his secretary. SO and SHEK are distributing the samples. SUM pays SHEK $5,000 for one bottle, which he plans to give LAI-SUM. HANG goes the couple’s apartment to ask for a sample. LAI-SUM refuses to let her have it. They both apply a thick amount of the product on their face, and both develop an allergy afterwards. The meeting with MRS. KUK, manufacturer of SFM, goes very well. YEE takes CHI to a hotel to celebrate. She invites him home afterwards, where she can show him her photos taken in Miami. He tells her he knew about her lie; she admits honestly. She even shows him a photo of them taken together. He is taken aback when she moves on to say they had a one-night stand seven years ago in Miami, and that they have a son called YIK-YEE.

SO takes a disc to SUM’s place to share with him some pornographic photos. SUM has copied the photos to his computer when he is trying to delete them. Not wanting LAI-SUM to find out about them, he throws away the computer right away. Unexpectedly, the cleaning worker takes it to the property management office. LAI-SUM, who happens to walk past the office, sees the computer as well as the photos. YEE is surprised YIK speaks fluent Sichuanese. He inquires into YIK’s background from his school and learns that YIK is not CHI’s son at all. YIK’s real mother, WAI CHING, is now in Mainland China. YEE asks SUM to look for CHING for him. LAI-SUM worries that SUM will take the opportunity to fool around. SIN teaches her to put away SUM’s home return permit, just as she has put away SO’s. What SIN does not know is, SO has applied for a replacement already. SO and SHEK make a fake home return permit for SUM so that he can cheat LAI-SUM……

SUM has found CHING. She tells him CHI is the girlfriend of MO SAT-KUEN, owner of the Mo & Gi Company. YEE decides to let CHI’s scam continue. LAI-SUM and SIN go to the mainland as soon as the FOUR KINGS have informed them of SUM’s whereabouts. SUM sees some red palm prints and warnings on the wall when he returns home. He calls his friends to come over to help him explain to LAI-SUM. They, nevertheless, make things worse. SUM agrees to a divorce each other unthinkingly. YEE goes to CHI’s place to tell her SFM’s quote. KUEN, who is hiding behind the curtains, could not be more pleased to hear this. YEE takes CHI to a massage parlor and unmasks her. CHING shows up out of nowhere and gives her a good telling-off. CHI is black and blue. What’s more, when she is home, she sees KUEN sleeping with a delivery girl. As if this is not enough, KUEN takes out some intimate photos of YEE and CHI and accuses her of betraying him……

LAI-SUM has once said that she will never forgive SUM because of one thing that happened on their wedding day. So everybody tries hard to recall what that was. LAI-SUM has decided to divorce SUM, saying that he was disloyal to her on their wedding night. The FOUR KINGS give SUM’s parents, CHING YEE-CHEUNG and HANG, a box. They tell the old couple there is evidence of SUM’s disloyalty inside. But they can only find a tissue with a lipstick mark and LAI-SUM’s wedding ring. After going through what happened on their wedding day in his mind, SUM finally figures out why LAI-SUM is so mad about him. Later, he takes her to the hotel, which she believes he took another woman to on their wedding night, to explain to her. With the help of YEE, he puts on what happened that evening. Everything goes very smoothly until YEE sees his ex-girlfriend, YAU KA-LEI, and her husband, MIKAMI, in the balcony of the next room……
