A few minutes ahead of the chambers hearing, trainee lawyer ROY finds out that he forgot to bring the letter issued by the consulate, so he requests another trainee solicitor, TONG CHING-CHI, to hurry back to the law firm and fetch the letter for him. Barrister FAN CHI-NGAI and solicitor LAM SUM-MUK begin the final preparation for the alleged abuse case of the domestic helper, and CHI-NGAI gets assistance from his pupils FOK TSZ-YING and CHAI ON-KUI. Following the questions posed by the prosecution barrister YAM CHUN-YIP, the accused MRS. KAM finally pleads guilty in the domestic helper abuse case, making CHUN-YIP's pupil YIU CHUI-FA admire her master very much. CHI-NGAI's wife, solicitor CHEUNG WAI-WAN is the partner of Woody Lam & Co, and she is very strict with her trainee TSANG HO-YAN. Even though, HO-YAN still has great respect for her……

ON-KUI and TSZ-YING rent an office in CHI-NGAI's chambers, officially starting their career. After WAI-WAN transfers the rich businessman LAU CHO-KWONG's case of alleged shoplifting to CHI-NGAI, ON-KUI has to handle the case all by himself in court because CHI-NGAI cannot make it to court. ON-KUI ends up feeling so nervous that he begins to throw up during the trial. When TSZ-YING starts looking for somewhere to stay, CHUI-FA hopes that either TSZ-YING and HO-YAN could sub-let a room to her after they find their ideal apartment. Knowing that CHING-CHI would like to resign and change her career to become a barrister, HO-YAN asks TSZ-YING to enquire on her behalf whether CHI-NGAI is going to receive another pupil into his chambers. CHING-CHI notices that there are cracks in the ceiling, yet she mistakes the structural engineer of the Buildings Department CHOW TSZ-BOK for the handyman……

Shortly after TSZ-YING moves in the new apartment, a resident who lives in the same building commits suicide. TSZ-YING is very afraid of ghosts, so she decides to sub-let the room to CHUI-FA after learning that living with CHUI-FA, who is very masculine in her attitudes and ways, could cast out evil and bring good fortune. Because barrister CHENG CHEUK-TUNG of CHI-NGAI's chambers is the opponent in the case that was handled by CHI-NGAI, ON-KUI becomes very defensive towards CHEUK-TUNG. Following CHI-NGAI to the parking lot, CHING-CHI directly asks CHI-NGAI whether he will consider to receive her as his pupil. With WAI-WAN reprimanding file clerk MAX for taking the easy way out, SUM-MUK tries to persuade WAI-WAN to leave it alone. WAI-WAN takes HO-YAN to a book store, where the owner CHU YIU-LIK recommends a book reading club to WAI-WAN……

When CHUI-FA moves into TSZ-YING's apartment, she also brings along the long-handled broadsword that has been passed down from generation to generation in her family, which upsets TSZ-YING. In the restaurant, CHING-CHI runs into KELVIN, who, maliciously, hints to CHI-NGAI that CHING-CHI is really a piece of work. TSZ-BOK consigns his computer to his friend's store for sale, using the name "M31" as the contact. Wanting to buy a second-hand computer, CHING-CHI then goes to contact the original owner M31. After CHI-NGAI interviews his client, a school bus driver called LI MING, who has been charged with causing death by dangerous driving, he goes to have lunch with PAUL and CHING-CHI, during which PAUL recognizes that CHING-CHI is the one who started her apprenticeship with KELVIN……

The case against LI MING is closed and LI MING is acquitted, as a result, CHUI-FA feels very sorry for her master CHUN-YIP, who instead teaches her that they should always remain expressionless regarding the litigation. In his performance appraisal, TSZ-BOK's supervisor, RICHARD, rates him low on each trait, so TSZ-BOK tosses his staff ID and leaves in a huff. When TSZ-BOK starts applying for pupillage, SUK-FUN tells him that CHI-NGAI is the best pupil master. Having found out that TSZ-BOK is going to take the PCLL exam and would like to become a barrister, CHING-CHI gives him some tips and tricks in preparation of the exam as a former student. Part time helper MARY goes to FAN's home for a job interview, and CHI-NGAI's son CHO-YIN hires her because he is satisfied with her work……

Recently, the law firm of TSZ-YING's Uncle CHARLES gets hired to deal with the case involving a star called SIT KIM, who is charged with assaulting a police officer, and they even want TSZ-YING to defend their client. While teaching CHING-CHI and TSZ-BOK in detail about the legal proceedings, CHI-NGAI constantly simulates the possible reaction of the accused so as to test their ability of dealing with the emergency. During her conversation with YIU-LIK, WAI-WAN learns about YIU-LIK's philosophy of life, following which she invites CHI-NGAI to drink sunflower tea together. Solicitor TSUI YIN-CHIT, who is handling the SIT KIM case, leads SIT KIM to go to have a meeting with TSZ-YING, during which SIT KIM has doubts about TSZ-YING's ability. However, YIN-CHIT reassures him that he should have faith in TSZ-YING……

After TAT-KAN recommends ON-KUI to defend LAM KIN-WAI, who committed the offence of jaywalking, ON-KUI, CHING-CHI and TSZ-BOK go to inspect the scene, during which CHING-CHI is very impressed with TSZ-BOK's active attitude towards work.

After WAI-WAN arrives together with her son CHO-YIN, JUDGE LUI recognizes that CHO-YIN is the one that often sits in and watches the trials, so CHI-NGAI and his wife start reprimanding CHO-YIN. Having invited her three good friends for a get-together in her home, HO-YAN not only prepares delicious food but also dresses up nicely, and all of her good friends have no idea what's going. At that moment, CHUNG-HANG arrives with a bouquet of flowers in his hands, announcing his and HO-YAN's upcoming September wedding.

With TSZ-BOK getting online at the office to chat with BLACK ANGEL and put forth his grievance, CHING-CHI finally comes to realize that TSZ-BOK is M31. CHI-NGAI and SUM-MUK's chambers jointly hold an annual vacation event, yet CHEUK-TUNG is unable to make it due to an emergency.

When ON-KUI is having lunch with TSZ-YING and CHUI-FA, he invites them to visit the jail with him. While there, CHUI-FA gets to know a prisoner CHAN KEUNG with a nickname called BROTHER LUNG. CHI-NGAI receives a new case, in which the witness for the prosecution is an underaged girl called WAN-SZE, whereas the accused is KAU PAK-TUNG.

With all the girls accompanying HO-YAN to conduct a site visit to the wedding venue, CHUNG-HANG, taking the advantage when HO-YAN is not around, asks TSZ-BOK to pick up CHING's phone call in his stead and lie for him. Seeing CHI-NGAI working out at the gym like crazy, CHUN-YIP assumes that it must have something to do with WAI-WAN, so he also mentions to him how he deals with the issues between him and CHEUK-TUNG. During lunch, CHING-CHI receives CHUI-FA's tips about how to lose weight, following which she alters the content a bit to make it appear as healthy living tips, and sends to TSZ-BOK in the name of BLACK ANGEL to trick him. In the case handled by ON-KUI and TAT-KAN, both the prosecution attorney and JUDGE HO think that the video is too blurry to be admissible evidence. However, ON-KUI insists to present it in court, making JUDGE HO feel so annoyed……

While TAT-KAN is going around in circles and trying to get some jobs done, WAI-WAN urges him to submit some documents as soon as possible, so SUM-MUK advises WAI-WAN not to be overly critical of TAT-KAN. Although some other jurors including CHING believe PAK-TUNG is guilty, CHAN TONG cannot make up his mind, so the jury has to continue to stay in court. CHING-CHI gives the wedding gift to HO-YAN, who hugs CHING-CHI and bursts into tears, worrying that she might have made a bad decision. HO-YAN assists TAT-KAN in dealing the job, which is spotted by WAI-WAN. WAI-WAN reprimands TAT-KAN for having HO-YAN do his job so as to get off work early, making TAT-KAN so angry that he resigns.

By chance, TSZ-YING overhears CHI-HUNG talking about KUN-TUNG's extramarital affairs. It's revealed that CHING-CHING has an illegitimate daughter. Having read about this, TSZ-YING seems to have felt something. CHEUK-TUNG is concerned that TSZ-YING would hate her once she learns about her real identity, so she confides her troubles to CHUN-YIP, who is the only one who knows her secret. When CHUI-FA and ON-KUI go for a visit at the jail, CHAN KEUNG introduces an inmate called KOON to CHUI-FA.

KOON has a belly ache and goes to the washroom, during which another prisoner SHEK HOI-SING also goes to the washroom to throw up. Accidentally, KOON loses his glasses, in the wake of which KOON is instead framed for beating up HOI-SING……

After HOI-SING and correction officer CHIU TING-YAU testify in court, CHUN-YIP is informed that CHAN KEUNG has suffered injuries and might not be able to attend the court hearing the following day, which makes ON-KUI feel suspicious. ON-KUI notices that CHUI-FA seems to be troubled after viewing the personal information of CHAN KEUNG, so CHUI-FA reveals to him that CHAN KEUNG could be her father, adding that she will never ever forgive him. With KOON and CHAN KEUNG giving their testimonies respectively, the prosecution attorney indicates that CHAN KEUNG made up a story so as to help get KOON set free. WAI-WAN goes to attend YIU-LIK's photography exhibition, where she discovers that she appears in one of his works called the "Secret Admirer".

CHEUK-TUNG enters a plea in mitigation for WAN-SZE. Although WAN-SZE receives a lenient sentence in the end, she shows no remorse at all. Wondering whether he should relocate his chambers to the 17th floor, CHUN-YIP even mentions about making room for CHEUK-TUNG to have her own office, but CHEUK-TUNG rejects his suggestion, adding that she will probably go overseas for a year to take a break. WAI-WAN spots some sexy girls' photos in CHO-YIN's tablet computer, so she reminds CHI-NGAI to ask their son about it. At midnight, WAI-WAN overhears that CHI-NGAI is talking on the phone. According to their conversation, the other end of the line requests to meet CHI-NGAI, whereas CHI-NGAI exhorts that person to learn how to handle things even without him being there. A professor complains that LI DAN often turns assignments in late, thinking that they should not be indulgent towards this……

TSZ-CHUN was CHING-CHI's neighbour after she emigrated to Australia, and also the schoolmate who inspired her to study law at University.

CHI-NGAI collects travel brochures to Easter Island and gives them to WAI-WAN, adding that he might be able to take the long vacation to accompany her, but WAI-WAN doesn't seem happy at all. Giving WAI-WAN a house key, YIU-LIK tells her that he has a summer resort, and she is welcome anytime. CHING-CHI, TSZ-CHUN, TSZ-BOK and HO-YAN go to take a tour around a remote island, during which HO-YAN accidentally slips and falls. Right away, TSZ-BOK picks her up……

Taking the advantage when his parents are away on a trip, CHO-YIN brings a female classmate, HAU-YUE, back home, but SUM-MUK suddenly pays a visit. CHING-CHI says that TSZ-CHUN wants to treat TSZ-BOK for a meal, coincidentally, HO-YAN arrives and sets off together with them. Rumor has it that CHI-NGAI sexually harassed a female student and all the staff who work in the chambers are gossiping about it. ON-KUI then reprimand them for talking non-sense, whereas TSZ-BOK, while reminding everyone not to assume anything, knows that CHING-CHI casts doubt on CHI-NGAI. SUM-MUK discusses the case with CHI-NGAI, thinking that the testimony given by the security guard is pretty much against CHI-NGAI. CHI-NGAI sends a text message to WAI-WAN, but receives no reply from her. On the other hand at the resort, YIU-LIK is trying to woo WAI-WAN with his cooking……

She also feels sorry for CHI-NGAI, knowing that WAI-WAN is not by his side, and CHI-NGAI has to confront this all by himself. Some police officers go to the chambers to ask CHI-NGAI to help with their investigation as they suspect CHI-NGAI is connected with an alleged rape. CHUI-FA wins the championship of the long-handled broadsword fighting, so TSZ-YING throws a party in celebration of her winning……

CHI-NGAI is concerned that his son might think too much after hearing all kinds of rumors, so he lets his son wear his barrister wig and pretend to be a judge to ask him for details about the issue. In the meantime, the police officers once again arrive at their home, requesting to take CHO-YIN back to the station to assist in the investigation for allegedly having a sexual relationship with a girl under the age of sixteen. While apologizing to CHI-NGAI and his wife for not having told them that CHO-YIN brought home a female classmate, SUM-MUK blames himself for lacking vigilance.
