An old guy called Kwan Wai is charged with murdering his paralyzed wife. Barrister Man Sun-hop is his defense counsel. He and female legal executive Chiu Ching-mui are using delaying tactics to let private investigator Kut Yat-ha gather evidence. With Inspector Kong Po-chai’s help, Yat-ha manages to track down Mrs Kwan’s attending physician. Visually impaired Shaw Mei-la is chatting with Sun-hop. But she then asks Yat-ha to investigate Sun-hop. A young girl called Chan Sze-ham is in a coma after trying to take her own life by jumping off a building. Her mother Lai Mei-yuet angrily accuses Dr Or Yue-lam of being the perpetrator. Ching-mui finds out Yue-lam had slandered Sze-ham online. Sun-hop takes this case because he finds out Sze-ham resorted to taking her own life as she ended up as a cyberbullying victim. Yue-lam’s father asks to see legal pundit Kan Siu-wang, who accepts this case as he realizes Sun-hop is the prosecutor.

Sun-hop feels depressed as he knows his antagonist is Siu-wang. He then runs into Mei-la. The duo have a drinking session. Sun-hop has not shown up the whole night. However, he returns and then asks Yat-ha to investigate Mei-la. Yat-ha tests Mei-la and finds out her secret. Yat-ha, Ching-mui and Sun-hop show up to reveal it. The prosecution and the defense in the Sze-ham case meet up. The chums are flabbergasted when Siu-wang tells them Mei-la is handling the case. Sun-hop offers his terms of settlement. Mei-la declines. Siu-wang reckons Sun-hop wants to create public opinion to facilitate him convincing the judge when it comes to jury selection. Mei-la raises her objection to the judge. But because of Ching-mui’s agitation tactics, she changes her mind. Yat-ha is deeply impressed by Mei-la. He is lectured by Sun-hop. Yat-ha hacks Sze-ham’s phone password and discovers Sze-ham’s recording before she plunged down the building.

Yat-ha and Po-chai track down Sze-ham’s female schoolmate, who helplessly reveals Sze-ham is a part-time girlfriend. But she points out Yue-lam and Sze-ham seem to be lovers. In the courtroom, Mei-yuet scolds Yue-lam for spreading rumors online about Sze-ham selling herself, resulting in Sze-ham being attacked by netizens. The jurors are sympathetic. Yue-lam points out Sze-ham is a part-time girlfriend. The two of them are not lovers as she has just chosen to fall in love with him. Mei-yuet wants to take her own life by jumping off a building when she hears Sze-ham’s last words. Kwok Lam offers to go to court to testify that Yue-lam and Sze-ham are seemingly lovers in exchange for her to become Sun-hop’s pupil. Mei-la invalidates Kwok Lam’s testimony by forcing Yue-lam to reveal some secret. Sun-hop uses his ultimate maneuver to arrange for an unconscious Sze-ham to testify in court.

An unconscious Sze-ham is agitated when Sun-hop tells her about Yue-lam slandering her, causing the judge to adjourn the hearing. Siu-wang arbitrarily looks for Mei-yuet. To stop netizens from attacking Sze-ham, Mei-yuet asks Sun-hop to withdraw prosecution. Sun-hop notices something when he reads online messages. He helplessly applies for withdrawal from prosecution. An old guy called Yau Yiu-hing is fatally run down by some lorry. Po-chai has witnessed Yiu-hing’s will, which designates a fresh-faced female companion called Chiu Ka-hei as beneficiary. Yiu-hing’s foster son Yau Sheung-choi has another version of Yiu-hing’s will. He asks Sun-hop to engage Ka-kei in a feud over his father’s estate. Ching-mui finds some clip that shows Yiu-hing was mentally unsound after the accident. Mei-la, who is Ka-hei’s legal counsel, points out some witness is to prove he was mentally sound.

Mei-la summons some paramedic, who gave first aid to Yiu-hing, to testify that he was mentally sound. Mei-la coaxes Yat-ha into covertly launching an investigation as she reckons Ka-hei is hiding something. Ka-hei has got into trouble. Yat-ha and Ching-mui come to her rescue. Sun-hop points out Yiu-hing wanted Ka-hei to be bequeathed with his personal estate, whereas Sheung-choi is to take over the family noodle shop. The two wills do not contradict. Mei-la points out Ka-hei is Yiu-hing’s daughter. But Sun-hop raises his objection and brings up the topic of New Territories indigenous inhabitants’ female offspring having no right of succession. The judge urges them to find Yin-hing’s son Yau Ka-kit. Sheung-choi and fellow villagers besiege Ka-hei in an attempt to make Ka-hei abandon the noodle shop. Ka-hei eventually reveals some shocking truth. While Sheung-choi is about to clinch the trophy, Mei-la tells Ka-hei she has a turnaround strategy.

Ka-hei ignores Mei-la’s advice and reveals her suffering over the years. Mei-la knows her case has no chance of winning. But Sun-hop covertly uses Yat-ha to guide Mei-la. Yat-ha finds out Ching-mui has signed up for PCLL. Ching-mui explains why she has not become a lawyer. At some mountainous location, police discover human remains and a condom nearby. Sun-hop and Yat-ha ask Po-chai about the incident. Po-chai points out the incident has something to do with a case involving some missing corpse that took place thirteen years ago. The remains are proved to be those of a missing girl called Ching Ho-yan. Hui Yat-tung was charged with murdering Ho-yan. Sun-hop could not prove Yat-tung’s innocence. Yat-tung was eventually found guilty and sentenced to prison. Yat-tung is moved when Sun-hop mentions lodging an appeal for him.

Secretary for Justice Fok Ting-bong invites Siu-wang to act as the prosecutor in the Yat-tung case. Siu-wang turns out to be the prosecutor who zeroed in on Yat-tung when Sun-hop was still his pupil. Siu-wang eloquently provoked Yat-tung to hurt himself, causing Sun-hop’s application for bail to fail. Sun-hop’s handling of Yat-tung’s appeal has caused people to turn against him. Even though Mei-la and Ching-mui persuade Sun-hop to abandon the case, Sun-hop insists on getting his way because a witness called Ho Mei-ching negated Yat-tung’s testimony and revealed the truth just before her death. Sun-hop urges Yat-ha to investigate some suspicious individual in the public gallery, who turns out to be Shek Heung-wing. He was another witness in the case. Po-chai arrests Tsang Siu-yau in connection with another case. Siu-yau claims she has clues regarding the Yat-tung case.

Sun-hop and his chums promptly go to see Siu-yau, who turns out to be Ho-yan’s schoolmate. She caught sight of Yat-tung and Mei-ching having some hanky-panky when the incident took place. Po-chai finds out Heung-wing was involved in some sex crime. But Heung-wing had an alibi. Sun-hop urges Yat-ha to come up with some way to collect Heung-wing’s DNA. Ching-mui pretends to be a masseuse. She obtains Heung-wing’s blood and takes it to a lab. Siu-yau goes to court to testify. But her testimony is questionable. Blood test results indicate Heung-wing’s DNA is different from the DNA in the condom beside the human remains. Yat-tung tries to take his own life. Sun-hop blames himself as Yat-tung passes out and is taken to hospital. Yat-ha finds out Heung-wing wants to smuggle himself out of Hong Kong. While the duo are scuffling, they fall into the sea. Po-chai rushes to the scene and saves Yat-ha. She also arrests Heung-wing and seizes this chance to collect his saliva.

Siu-wang deliberately lets Heung-wing act as prosecution witness. He prevents Sun-hop from approaching Heung-wing and also Mei-la from intervening. Lab tests results indicate Heung-wing’s DNA corresponds to the DNA in the condom beside the human remains. The judge rejects the evidence as it has been obtained by illegitimate means. Mei-la covertly investigates and promptly tells Siu-wang what she knows. But Siu-wang ignores her. The judge reprimands Sun-hop for daringly revealing everything. Mei-la earnestly offers to go to court to testify for Sun-hop. Regrettably, Siu-wang is not affected by this maneuver. Sun-hop suspects CCTV footage showing Heung-wing leaving the incident location has been tampered with. But it cannot be presented as evidence in court. Siu-wang unexpectedly makes a preemptive move by lodging an application for withdrawal from prosecution.

Mei-la asks Yat-ha to investigate whether construction worker Lau Kin-fung has faked his injury. Yat-ha knows Kin-fung and his counterparts Chan Fook-chuen and Chiu Yu-heen are “fast food restaurant vagabonds”, so he pretends to be a rough sleeper and mingles with them. Yat-ha tells Mei-la he is quitting as he sympathizes with Kin-fung, who wants to get the compensation and help an injured Fook-chuen with the money. Kwok Lam helps an old lady called Auntie Fook apply for adverse possession of staircase space in some building. A homicide has taken place in some back alley outside the staircase. Fook-chuen become a murder suspect. At Yat-ha’s request, Sun-hop agrees to help Fook-chuen. But Fook-chuen admits he is the killer. The chums go to some subdivided unit in the staircase space. They unexpectedly find some photo of Burmese tenant Zaw and Tai Tin-yan. Sun-hop and his chums go to Tai O to look for Zaw as they want to ask him to act as a witness. Someone promptly follows them.

Smith, who is Burmese-Chinese, hooks up with Sun-hop and his chums. He points out Zaw has coaxed his own fiancée Maya into coming to Hong Kong. He hopes he can find some news about them. Yat-ha and his chums track down Zaw. In the process, Sun-hop runs into Maya. But she is quickly taken away by Smith’s minions. Zaw tells the chums Maya’s parents offered some piece of land as betrothal gift. Zaw is adamant that he has to save Maya first, so he cannot testify in the Fook-chuen case. Sun-hop promises to save Maya. Kwok Lam and Po-chai ask Fook Chuen if there are more details in the case that they should know. He is certain there was not any third person at the death scene. Sun-hop and Smith’s negotiation comes to nothing. Smith tells his minions to chuck Sun-hop into the sea.

Prosecutor Wah Chun-ngok mentions the Fook-chuen case is going to trial after three days. Sun-hop urges Kwok Lam to look into her father’s Kwok Yat-fan’s group business. Zaw takes some clip and then leaves. He reveals everything he knows about the Fook-chuen case. He also mentions the late Tin-yan had certain regrets. Sun-hop knows Smith’s wish to get his hands on the Mayas’ land has something to do with Yat-fan, so he threatens to expose Smith’s shenanigans, unless he lets Maya go. Meanwhile, Zaw and his chums and Yat-ha have covertly come to save Maya. But their mission fails. Smith is going to kill the chums. Mei-la takes Sun-hop to some forest mentioned by Tin-yan. Sun-hop abruptly knocks Mei-la out.

Sun-hop goes into the forest alone and is about to take his own life. Mei-la rushes to the scene and manages to intervene. The duo tearfully embrace each other. Ching-mui and Yat-ha promptly show up and see what is happening. They are devastated and resort to drinking their sorrows away. They kiss and spend the night together. After waking up, they are then afraid of people finding out they have slept together. They just have to keep this a secret. Sun-hop requests that Zaw is allowed to testify by video link. Yat-ha also convinces Fook-chuen to plead not guilty. In court Zaw points out there was some third person at the death scene, but he did not see their face. He is quashed by Chun-ngok. After recess, Kin-fung also begins to suspect Fook-chuen. Yu-heen gets furious and starts an argument with Kin-fung. In court Sun-hop asks Fook-chuen who was the third person at the death scene. Fook-chuen is so frustrated that he passes out.

Yat-fan, on behalf of the business fraternity, wants Siu-wang to side with their camp. He offers to finance the construction of some law school on the condition that Siu-wang is elected as Chairman of the Hong Kong Bar. Sun-hop deliberately makes Fook-chuen stay at hospital as he needs more time to track down the third person at the death scene. Yat-ha is certain Yu-heen is the main suspect. Mei-la objects to Siu-wang running for chairman. Siu-wang is adamant that he will not let business people get in his way. Yu-heen goes to see Fook-chuen. Po-chai helps Yat-ha scam Yu-heen by falsely claiming Fook-chuen has some terminal illness. Siu-wing asks Sun-hop to be his running mate. Sun-hop declines. But Siu-wang tells outsiders he has won Sun-hop’s support. Yu-heen agrees to go to court to testify. But some traffic accident takes place on the way. Fook-chuen is dejected and does not want to defend himself anymore. The chums try their best to dissuade him, but to no avail.

Fook-chuen does not want to defend himself anymore. Sun-hop wants to give up as he fails to dissuade him. Sun-hop attracts criticism as he uses the press to scold Fook-chuen. Yat-ha, Ching-mui and their chums hope they can retrieve Yu-heen’s blood stained clothes as they want to prove he was at the death scene. But they have to overcome hurdles. Siu-wang lends a helping hand. Sun-hop helplessly agrees to his request. Mei-la eventually finds some blood stained garment. Regrettably, she is rebuffed by Chun-ngok in court. Sun-hop then asks Fook-chuen if he had killed someone. Fan Sai-cheong, who is Siu-wang’s opponent in the Hong Kong Bar’s leadership election, seeks Sun-hop’s support, but he fails. Sai-cheong is worried about Siu-wang and Yat-fan having arbitrarily reached some agreement. He reminds Sun-hop not to rally for Siu-wang. Ching-mui’s father Chiu Cheung-fung thinks Ching-mui is pregnant. He is certain Yat-ha is involved.

Cheungfung wants to bury Yatha alive.He also questions Chingmui about her pregnancy.Yatha saves himself by falsely claiming he and Chingmui are in love.Siuwang hosts a banquet to improve public relations in the legal fraternity.Sunhop outlines his standpoint and then leaves.He and Meila turn against each other.An actress called Yiu Man is taken to hospital as she has a heart attack.Yatfan urges Dean Or Bokyuen to perform heart transplant surgery on her as soon as possible.Police are cracking down on clandestine shooting shenanigans.Po-chai notices someone has taken footage of Yathan and Chingmui, which can be used to determine the nature of the duo’s relationship.Lau Chisum, who was drawn into a poisoned dog case, clashes with with Bokyuen.Actually, his mother Ma Yuyuk was supposed to undergo heart transplant surgery, but Yiu Man jumped the queue.Chisum asks Sun-hop for help.Yatfan asks Siuwang to take this case.Siuwang organizes a press conference to let Yiu Man explain her condition.

Sun-hop uses his fourth sense to determine that Yiu Man has healthy limbs. He reckons her condition is not as bad as it seems. Yue-lam and Mei-la offer their terms of settlement to Chi-sum and his mother. Chi-sum declines. For Chi-sum’s sake, Yu-yuk then wants to accept the compensation. However … Yat-ha sneaks into Yiu Man’s ward and installs some camera. But Mei-la advises Yiu Man to change ward as she finds out there has been some intruder. Sai-cheong’s original campaign team is ruined by Siu-wang. Before going into the courtroom, Sun-hop announces he is to run for Chairman of the Hong Kong Bar as he wants to provoke Siu-wang and affect his performance. But Siu-wang sees right through him. Sun-hop wants to find Yiu Man’s movie clips to prove her health condition. Yat-ha and Po-chai manage to find some clip. Yat-fan sends his people to intervene. The duo have an accident.

Sun-hop has gathered evidence and questions Yiu Man. But he is refuted by Siu-wang. Ching-mui sympathizes with Yu-yuk. She arbitrarily approaches Siu-wang as she hopes he can reconsider the terms of settlement. She is turned down. Yat-ha argues with Sun-hop as he objects to letting Chi-sum testify in court. Sun-hop accidentally finds out Chi-sum has amazing memory. In court Sun-hop puts on a clip showing Bok-yuen’s phone conversation. He points out Chi-sum heard Bok-yuen requesting test results to show Yiu Man to be more poorly than Yu-yuk. Siu-wang points out Chi-sum’s previous illness had greatly affected his hearing. Mei-la takes photos of Yiu Man’s medical records and goes to question Siu-wang. She also lets Sun-hop and his chums listen to everything through her phone. She turns against Siu-wang. Siu-wang tells Yat-fan to lure Yu-yuk into withdrawing her complaint. Sun-hop objects to Yu-yuk giving up.

Yu-yuk signs some paper to acknowledge receipt of Yat-fan’s donation. Ching-mui and Sun-hop take her back to the hospital. They run into Yiu Man, who is going somewhere due to some matter. Ching-mui’s vehicle hits Yiu Man’s car. Mei-la sets up shop and accepts a legal aid case. The victim is called Kam Lan, and her son Lok Wai-to had died in an industrial accident. Kam Lan has received compensation from her son’s employer. Wong Wai-shan, who claims to be Wai-to’s wife, then showed up. Kam Lan points out she is only after the money. Ching-mui introduces a client to Kwok Lam, and the client turns out to be Wai-shan. Yat-ha helps Mei-la investigate Wai-shan. He finds out she had applied to divorce Wai-to. But she withdrew her divorce petition after Wai-to’s death. Siu-wang uses his influence in an attempt to make Sun-hop stop running for Chairman of the Hong Kong Bar. Sun-hop attends the debate alone. He tells Siu-wang he will not abort his election campaign.

After the debate with Siuwang, Sunhop has won over many new supporters.Yatfan decides to covertly deal with Sunhop.Meila suspects Waishan and Waito’s marriage was fake.Yatha finds out Waishan had deposited HK$100,000 into Waito’s account. Chingmui asks Sunhop for help as she is worried about Kwok Lam losing out to Meila.Sun-hop points this case is going to test Chingmui.Waishan goes to court to testify.Meila keeps attacking her. Chingmui, on behalf of Kwok Lam, brings up counterarguments.Sunhop appreciates her performance.Meila asks Waishan’s fellow native Yuen Mankuen to testify. She points out Waishan was looking for some way arrange a fake marriage. She even borrowed HK$100,000 from her, and the money was to be used as a reward for her pretend husband.Sunhop agrees to be interviewed by Ting Ning, who was Sunhop’s younger fellow female student in Sunhop’s college days.Ting Ning feels unwell after the interview. Sunhop holds her and sits her down.Lipstick marks are left on his shirt.

Kwok Lam persuades Waishan to settle the case. Chingmui raises her objection and asks Sun-hop for help. Sun-hop emphasizes Kwok Lam is Waishan’s legal counsel. Yatha unwittingly overhears Kam Lan and her friend’s conversation. Kam Lan in fact knew Waito and Waishan’s marriage was genuine. Meila persuades Kam Lan to consider settling the case. Siuwang tells Chingmui certain clues that could help her win. He also mentions some terms of exchange. Waishan and Kam Lan want to sign the settlement agreement. Chingmui asks Sun-hop to come up with some way to intervene.Chingmui actually finds out Kam Lan once drugged Wai-to to prevent him from going to school when he was a primary school pupil because she did not want him to mix with the wrong crowd.Chingmui again approaches construction workers and questions them.She finds out ..Siuwang forces Chingmui to do something as she has promised.Sunhop slyly deals with this matter.He thinks he has settled the issues, but there is yet another accident.

Sunhop is charged with indecent assault. Siuwang goes to ask Yatfan to tell him the details about this case. Siuwang then reckons Yatfan has not done anything improper. Chingmui is certain Siu-wang is taking revenge on Sunhop because Siuwang is not happy about her not keeping her promise. She vents her anger by taking her people to vandalize Siuwang’s car. Chingsmui is confounded as Siu-wang wants her to deliver his message to Sun-hop telling him to refrain from further shenanigans. But Sun-hop seems to understand his meaning. The Hong Kong Bar revokes Sun-hop’s election candidate status. Siu-wang naturally becomes the new chairman. While Yat-fan and Siu-wang are going to some place to celebrate, they run into Sun-hop on the way and a fracas ensues. Siu-wang lets Yat-fan leave first. Yat-fan then accidentally runs down some pedestrian. The antagonist has even taken some footage and threatens him. Sun-hop goes to the hospital to see Cheung-fung, who asks Sun-hop to do something for him.

Sun-hop uses some excuse to terminate his chambers’ contract with Ching-mui and expel her. Ching-mui is so frustrated that she decides to go to the UK to complete her legal course. Cheung-fung is overjoyed. Mei-la questions Sun-hop’s decision. Sun-hop deliberately clings to Mei-la as he notices Ching-mui has come. Ching-mui is heartbroken and leaves Hong Kong alone. She still thinks of Sun-hop before her departure. Meanwhile, Mei-la accepts an invitation to join Department of Justice and become a prosecutor. One day, Yat-ha and Po-chai witness some knife-wielding perpetrator randomly hurting people. Police offer reward for information to find a suspect called Cheung Kam-mun. Yat-ha manages to lure Kam-mun into showing up. Yat-ha and Po-chai go after the suspect via two routes. Soon after, Po-chai is shocked to see a seriously wounded Yat-ha lying in some staircase at the back.

Po-chai gets hysterical when she sees a seriously wounded Yat-ha. She goes to the roof to catch Kam-mun. The duo scuffle. Po-chai is beaten. Kam-mun even snatches her gun. Meanwhile, sound of gun shots echoes across the roof. Po-chai rushes to the hospital to see a wounded and bedridden Yat-ha. She feels sorry. Yat-ha comes round. The chums are frustrated as he keeps thinking of offering some reward. Po-chai is accused of murder. Mei-la is the prosecutor in this case. She also objects to Po-chai to be released on bail while awaiting trial. Yat-ha scolds Mei-la. Sun-hop and Kwok Lam go to some roof opposite to the incident scene in an attempt to find witnesses. Meanwhile, they find some rough sleepers on the roof. Yat-ha then notices a certain rough sleeper has left the roof. He goes after them and eventually finds a rough sleeper called Lee Biu.

Kwok Lam asks Kam-mun’s acquaintance to testify. His acquaintance claims Kam-mun once predicted he would achieve something and also mentioned his wealthy family. But Mei-la manages to prove Kam-mun is a liar. Sun-hop is in an adverse situation. Mei-la has found some important clue. She decides to covertly tells Sun-hop about it. Po-chai’s case is concluded. Meanwhile, Cheung-fung has a relapse and is taken to hospital. Fast-forward three years and Sun-hop is appointed as Senior Counsel, and Mei-la has also become Deputy Director of Public Prosecutions. The duo congratulate each other. Sun-hop hears some familiar footsteps nearby. Someone and the chums nearly run into each other. Tycoon Chow Ka-lai and his assistant Woo Kai-yi have raped rookie actress Wong Chi-yue. Ka-lai asks Ching-mui, who is Siu-wang’s new pupil, to act as his defense counsel.

Ching-mui suggests Sun-hop act as second defendant Kai-yiu’s defense counsel. Yat-ha in fact already knew Kai-yin in his childhood days. He convinces Sun-hop to lend a helping hand. But Sun-hop is not interested. Kai-yin tells Sun-hop Ka-lai has always taken care of him. He also explains how he committed a blunder due to Ka-lai’s coercion. Sun-hop decides to defend him after hearing his story. Ching-mui has the upper in the courtroom. Mei-la thinks she is another Siu-wang. Meanwhile, Ka-lai asks to see Yat-ho as he finds out Yat-ha has bugged his car. Ka-lai again frames Yat-ha by abruptly bruising himself. Yat-ha cannot offer any satisfactory explanation. And then Ching-mui offers certain certain terms of exchange to Sun-hop.

Chi-yue is overwhelmed by public opinion and refuses to go to court to testify against Ka-lai. Fortunately, Mei-la encourages her to pick herself up. Yat-ha is furious as he knows Sun-hop is forced to abandon the case. Sun-hop comes up with a scheme that eventually causes Ka-lai not to testify against Yat-ha. Ching-mui is going to summon Ka-lai’s wife Ma Suk-yee to testify in court. But Suk-yee suddenly disappears. Sun-hop and his chums promptly find Suk-yee. Mei-la manages to convince her to testify that Ka-lai has committed crime. While Sun-hop and Kwok Lam are escorting Suk-yee away, they get into a precarious situation as some assassin goes after them. Mei-la gives up her prosecutor job and becomes Sun-hop’s defense witness. Ching-mui sees right through Mei-la and reveals her secret in front of other people. Mei-la is utterly devastated.

Yat-ha is determined to get to the bottom of the problem. He retrieves some important exhibit from some car wreck on the seabed. This has enabled Sun-hop to turn the situation around for the time being. To win the case, Ching-mui and Ka-lai are plotting to fabricate some medical report. Meanwhile, Mei-la is abruptly kidnapped. Sun-hop is forced to agree to Ka-lai’s terms. Ka-lai is full of himself in the courtroom. Meanwhile, a new witness is summoned to testify in court. The elegant lady sexual assault trial is concluded. Yat-ha tells Mei-la he loves her. Mei-la agrees to be his girlfriend and kisses him as she is moved by his sincerity. Siu-wang returns to Hong Kong and asks to see Mei-la’s trio. Mei-la reminds Sun-hop to treasure someone he loves. Sun-hop finally makes an important step. However …
