Chung-ying does not like what she sees. She imitates Pik-kei’s way of seducing Lik-kei. Ho-fan notices something strange when he is having a text conversation with Sau-chun. While Ho-fan is tidying up Sau-chun’s clothes, he discovers some photo. He then promptly has a migraine as he recalls certain moments during that day when his mother died. Chung-ying catches sight of Pik-kei and Lik-kei’s affectionate gestures. She gets angry and tells Lik-kei she wants to end their relationship.

She wrongly thinks Ming-kwan is Chun-tung. She also scolds him for taking Lai-yiu away. Lik-kei begs Chung-ying to pretend to be Lai-yiu and ask Sau-chun about Lai-yiu’s background.

Wing-yum seizes a chance to peep at Lik-kei’s phone. She notices some clip showing her ugly and messy self. Wing-yum and Chung-ying are agonizing over this.

While Lik-kei is confronting Lai-yiu, he realizes she has something to do with his father’s death.

Lik-kei and Chung-ying inspect some suspicious batch of apparel. But they have not found anything. Ho-fan then wants to sort out the apparel. While he is ironing some garment, each of the trio becomes disoriented one after another. The next day, Chung-ying surprisingly sees Li-kei sleeping in the same bed as her. They have even mutually switched clothes between them. The same things have also happened to Ho-fan and Wing-yum. But the quartet cannot remember anything about last night. Chung-ying goes along with Ho-fan to undergo hypnosis in an attempt to retrieve lost memories. But Ho-fan cannot be hypnotized. Instead, Chung-ying recalls she and Lik-kei taking footage of themselves the other night. But that clip is not on her phone. W reminds Lai-yiu not to let anyone know her whereabouts. Lai-yiu then moves into the Yip household. Ming-kwan helplessly agrees. Lik-kei tells Ming-kwan to get closer to Lai-yiu to gather intelligence.

Lik-kei tenders his resignation. Sun-wai asks him to stay. Wing-yum asks to see Sun-wai. She questions him if he has been doing his daughter’s homework. Sun-wai changes the topic by mentioning Lik-kei’s resignation. He also seizes a chance to leave. Wing-yum anxiously tells Lik-kei’s subordinates about Lik-kei’s intention to resign. Hok-yan and Lik-kei even turn against each other. Chung-ying is tracking Lai-yiu. A bunch of thugs abruptly goes after Chung-ying, who calls Lik-kei and asks for help as the situation gets dangerous. Lik-kei promptly comes to Chung-ying’s rescue. Chung-ying has taken photos of some suspicious woman. Ho-fan notices some tattoo on the back of the woman’s neck. He then asks Hok-yan about what he has noticed. Lik-kei and his subordinates tail the woman. With Wing-yum and Chung-ying’s help, he eventually manages to take clear pictures of the woman’s tattoo pattern. Lik-kei suspects Lai-yiu has something to do with the narcotics case.

Lik-kei and his chums catch sight of Chun-tung’s female accomplice Lai-yiu outside the police station. Lai-yiu reveals certain details in Chun-tung’s homicide case. Cheung-lok begs Chung-ying to let Lai-yiu become deputy general manager of the company. Although Chung-ying does not think Lai-yiu is up to the job, she still agrees as she is empathetic. But Lai-yiu actually has some ulterior motive. Lik-kei has a date with Chung-ying, who undergoes a makeover and goes out with him. But Lik-kei has also asked his subordinates and Ho-fan to come along. Chung-ying is somewhat disappointed as their rendezvous has some other meaning. Ho-fan shows up to ask to see Lik-kei. He wants to tell him Pik-kei is having an affair.

Lik-kei and his subordinates manage to get CCTV footage of the incident on that particular date from Chung-ying’s team. They then go to the incident location to gather evidence. They find some dash cam that could have recorded the course of events. Lik-kei tracks down car owner Kam Chi-shing. He also notices the dash cam footage has captured some woman’s voice.

But Wing-yum abruptly shows up with Ho-fan’s authorization letter, which designates her as his representative in handling company matters.

At the police station, Lik-kei directs Ho-fan to look for the baddies. A certain target turns out to be Ching-ying’s subordinate. The case is concluded. Ho-fan and Chung-ying want to express their gratitude to the chums by inviting Lik-kei and his relatives and also his subordinates to dinner. During the proceedings, Chung-ying catches sight of Lik-kei and Pik-kei constantly clinging to each other. Ho-fan is bothered by regularly seeing images of Lik-kei in his head. He then makes an appointment with some psychotherapist. He also asks Lik-kei to help resolve issues of seeing him in his dreams. Wing-yum accidentally finds out Ho-fan is a committee member of the school where she works. She then uses him to save face in front of the principal. W asks Ming-kwan to settle his debt. However, Ming-kwan fails to convince Cheung-lok to sign the document for machinery purchase. Ming-kwan wants to kidnap Ho-fan and force Cheung-lok to sign the document on behalf of his boss.

Lik-kei tries to help Ho-fan retrieve lost memories by forcing him to drink. Chung-ying is furious after finding out Lik-kei’s antics. Pik-kei is requested to repay her debt. Wing-yum’s home is doused with kerosene. Pik-kei gets nervous and calls Lik-kei and asks for help. Lik-kei tells his subordinate to stand in for him and protect Ho-fan. He then wants to rush home, resulting in some baddie seizing this chance to enter the place and shoot Ho-fan, who is on the brink of death. Chung-ying gets furious as Lik-kei has done a bad job. Ho-fan then unexpectedly wants to move into Lik-kei’s home. Wing-yum is annoyed as electrical appliances and furniture are repositioned. On Lik-kei’s advice, Chung-ying investigates the incident involving some snitch in the company. She also uses the CCTV hard disk to lure the snitch into showing up. Lik-kei takes Ho-fan to the police station. Ho-fan suddenly claims he is smelling the assassin’s odor.

Lik-kei, Ho-fan and Chung-ying are evading the baddies. In an elevator, Lik-kei abruptly has breathing difficulties and collapses. After being pursued by assassin, Ho-fan keeps hiding in his room all day long. He is only willing to contact Lik-kei. Crime Unit tells Lik-kei to resume duty and protect Ho-fan. The duo are polar opposites and often get into hilarious situations. Ming-kwan is really scared as tough guy W wants him to settle his debt. To raise money, Ming-kwan uses some excuse for buying new machinery to embezzle company funds. But some document requires Ho-fan’s signature. Ho-fan refuses to sign as he notices some error on the document. Ming-kwan is frustrated. Lik-kei wants to track down the female accomplice mentioned by Ho-fan. He finds out Rising Apparel Limited has exactly lost the key date’s CCTV footage.

Lik-kei catches sight of Chun-tung while he and his subordinates are raiding some brothel. Lik-kei pursues him and reaches some unit. Ho-fan follows from behind and notices Chun-tung’s female accomplice. Chun-tung is restrained by Lik-kei in a back alley. Some assassin fatally shoots Chun-tung and even points a gun at Ho-fan. Lik-kei instinctively pulls Ho-fan away. But Ho-fan accidentally bruises his head and passes out. Ho-fan comes round and then cannot recall the course of events in the shooting incident. But he remembers he had seen Chun-tung’s female accomplice in the office.

Lik-kei goes to see Ho-fan. He suspects someone is going to harm him. Suddenly, a gun-wielding mysterious person snipes at Ho-fan.

At some betting shop, while Sergeant Ko Lik-kei is agonizing over raising money for settling his girlfriend Tai Pik-kei’s debt, pickpocket Yuen Chun-tung snatches his wallet. Lik-kei and his subordinate go after Chun-tung. But Inspector Chung Ching-ying jeers at them as he is one step ahead. A witness called Lee Ho-fan goes to the police station to make statements. His legal counsel Lee Chung-ying insists that Ho-fan is not going to be a witness. She and Lik-kei keep arguing. Ho-fan picks up Lik-kei’s wallet in which he finds Lik-kei’s card. Ho-fan then calls Lik-kei. But because of Ho-fan’s stubborn character, Ho-fan and Lik-kei misunderstand each other. Ho-fan is the chairman of Rising Apparel Limited. He and his younger sister Chung-ying, who is a barrister by profession, are going to a product launch event hosted by senior staff member Yip Ming-kwan. Ho-fan accidentally causes Ming-kwan to embarrass himself at the event.
