As a nurse, SIN-HANG not only looks after CHI-LIK's health, but also deals with the political infighting of CHI-LIK's company. After having her car rear-ended by a truck, SIN-HANG demands indemnities from the truck driver, who then suffers a heart attack while driving away for fear of having no money to pay. Fortunately, an off-duty police officer YUEN SHIU-GAT riding a bicycle passes by, helping the driver out of trouble.… ...

With CHI-LIK being admitted in hospital, some changes have taken place in his company. KY, who claims to be a co-founder of the company, seizes the opportunity to convene a board meeting, coercing CHI-LIK to let him take over the management. A cakery owner reports to the police that he has suffered repetitive property damages by someone anonymous and suspects it was the deed of a land developer regarding property acquisition, so SHIU-GAT brings along YAT-SHAN there for the on-site investigation. YAT-SHAN takes SHIU-GAT to a nursing home to visit his grand aunt LUK YUNG, but SHIU-GAT leaves early after suddenly receiving a tip-off regarding a tattooed brothel client.

Understanding his time is limited, CHI-LIK hopes SIN-HANG will continue the development of the sleepless city, and he even makes his will as he feels that he has already reached his time. With her credit card being due, plus her landlord demanding the rental payment, SZE-KA comes up with an idea to obtain SIN-CHI's new mobile phone by deception. CHI-LIK does not even have the strength to utter a word, so he blames YAT-SHAN for failing to heal him of his sickness.

The man whom SHIU-GAT met looks alike YAT-SHAN very much, and he turns out to be YAT-SHAN's twin brother YUET-SHAN. YUET-SHAN merely resembles his elder brother in looks, in fact, he is a trifler, living by his wits. When visiting LUK YUNG, SHIU-GAT thinks that YUET-SHAN has already informed her about YAT-SHAN's death, unexpectedly, YUET-SHAN shows up in the nursing home wearing clothes similar to his late brother YAT-SHAN. CHUN-PING and YAT-FEI are enthusiastically preparing for their wedding ceremony, during which the two argue a bit as YAT-FEI wants to devote herself in social work.

In his business report, CHUN-PING states that the progress of the sleepless city is hindered due to KY's action on the sly. Furthermore, someone is reportedly promoting natural volcano beauty mud, which arises SIN-HANG's interest, so she orders CHUN-PING to probe into it.

SIN-CHI's father has made great improvement in recovering from his illness.… ...

YUET-SHAN learns from SZE-KA that SIN-HANG and CHUN-PING have lost company money in bad investments, so he hints it vaguely to CHI-LIK. Right after SIN-HANG returns, CHI-LIK asks about the reason behind her alleged involvement in the embezzlement, triggering an argument between the pair. On the other hand, YAT-FEI goes to seek SIN-HANG's advice because CHUN-PING is often too busy to talk to her. CHUN-PING knows that it's YUET-SHAN who has blabbed to CHI-LIK, therefore SIN-HANG alerts CHUN-PING to keep an eye on YUET-SHAN to avoid letting the latter supersede him in the company. SHIU-GAT pays tribute to the late YAT-SHAN on his birthday, ahead of which YUET-SHAN has already arrived there to pay his respects to his late brother.

Having returned home, CHI-LIK breaks the deadlock in his relationship with SIN-HANG, and SIN-HANG also knows that he has been with SHIU-GAT the whole night. Upon her return, SHIU-GAT sees that YUET-SHAN and SZE-KA end up in the same bed, so she gets really mad and drives away YUET-SHAN. In a restaurant, waiter YUK all of a sudden grabs a knife to attack SZE-KA.

With CHI-LIK once again suffering injuries for saving SHIU-GAT, SIN-HANG cannot refrain from getting jealous at SHIU-GAT. On the flip side, CHI-LIK who is determined to make a match between SHIU-GAT and YUET-SHAN says he will do all in his power to help YUET-SHAN. In order to get close to CHI-LIK, SHIU-GAT purposely goes to the restaurant that CHI-LIK often visits, and takes away the wine glass for lab testing. Despite being stopped by SHIU-GAT, SIN-CHI still pays a visit to CHI-LIK's home by taking advantage of visiting his own sister so as to investigate CHI-LIK's past. Occasionally, YUET-SHAN spots that KEN from his company socializes with some problematic clients and smells something fishy, so he joins forces with SZE-KA to investigate KEN.

Eventually, YUET-SHAN manages to move SHIU-GAT. Though SHIU-GAT has accepted YUET-SHAN, she appears reluctant to start a relationship with him. SHIU-GAT knows that she must probe into KY who endured hardship with CHI-LIK from the very beginning if she wants to investigate CHI-LIK's past. When KENG-SHUI urges SIN-HANG to make up her mind on their joint venture to build some film studios as soon as possible, SIN-HANG comes to realize that KENG-SHUI's real intention is to launder money under the disguise of the entertainment industry. SIN-HANG attempts to appoint CHUN-PING as the business decision-maker in order to get a green light for her film studios investment, so she tries to wheedle each shareholder into voting for promoting CHUN-PING. Though CHI-LIK agrees with her, he suggests promoting YUET-SHAN to his special assistant, reporting directly to him.… ...

SIN-HANG feels really disappointed when she knows that CHI-LIK is going to check the financial statements of her modeling company, so she goes to talk to CHUN-PING, venting her grievances. When CHUN-PING returns home, he is thrilled with joy after YAT-FEI tells him that she is pregnant. SHIU-GAT receives a phone call from YUET-SHAN, who asks her to hurry to an industrial building. Upon her arrival, she sees that YUET-SHAN formed a band with some young guys and are playing music, so she feels that she was just worrying too much. When checking CHI-LIK's pulse during a follow-up consultation, SIN-CHI notices there is a dragon tattoo with some lettering namely "POWER" on his arm. CHI-LIK receives a phone call from his old friend CHU CHUNG-YAN. It turns out that CHUNG-YAN wants to blackmail CHI-LIK as the latter appeared in the industrial building which was a murder crime scene.… ...

The testimony given by a security person of the industrial building, HUNG SHU-GAN, indicates that he saw YUET-SHAN tangle with VENASSA.S over something, which seems very much against YUET-SHAN. SHIU-GAT cannot investigate the case because YUET-SHAN is her boyfriend, so she has to probe into the matter in private. With SIN-CHI's help, SHIU-GAT deduces that SHU-GAN has given false testimony. In the general meeting of the shareholders, someone suggests dismissing YUET-SHAN, but SIN-HANG reverses her attitude towards YUET-SHAN, covering him up. SAI-KAU presents new evidence with regard to SHIU-GAT's mother, SHIU-LAN's murder case. SHIU-GAT learns about CHI-LIK's running routes, where she manages to get CHI-LIK's hair sample for lab testing. Having the mindset that CHUN-PING is having an affair, YAT-FEI goes to discuss this with SIN-HANG, who convinces her to endure it for the sake of her unborn child.… ...

While SHIU-GAT is recording SHU-GAN's statement, SHU-GAN insists that he did not kill anyone in the past. Following wide media coverage on the matter of SHU-GAN, WING-YAN comes to realize SHIU-GAT's bygones, and YUEN-SUM is also concerned about her very much. CHI-LIK makes an appointment with SHIU-GAT, making it clear that SHU-GAN is not the murderer. In a convenience store, SZE-KA lays bare the evil plot when a man tries to rape a girl by drugging her, which is video recorded by a passer-by and put on the internet with SZE-KA being called a "Scum Killer". Moreover, she participates in a movie production of the event. YAT-FEI asks CHUN-PING whether he is having an affair. CHUN-PING instead pleads his drunken misbehavior. Suspecting that KENG-SHUI's true intention behind his investment is for money laundering, CHI-LIK refuses to cooperate with him.… ...

CHI-LIK convenes a meeting of the shareholders where he explains the issue of surrendering himself to the police. Apart from that, he also appoints YUET-SHAN to be the substitute chairman of the company. In the meeting, YUET-SHAN proposes re-designing the Sleepless City, and transferring the funds of the filming studios to the Sleepless City, but is rejected by SIN-HANG and CHUN-PING immediately. SZE-KA persuades YUET-SHAN that he should not cross SIN-HANG anymore in light of the fact that the chairman is no longer in the company. WING-YAN turns down SIN-CHI when the latter shows his affection for her. While the two are tangling with each other, to their surprise, they see SIN-HANG and CHUN-PING hugging and kissing each other. YUET-SHAN goes to CHI-LIK's home to report to him. After learning that YUET-SHAN's power in the company is usurped, CHI-LIK cannot help feeling disappointed at his wife.… ...

SZE-KA is concerned that SHIU-GAT and YUET-SHAN gradually become estranged, whereas SHIU-GAT considers that each of them has different points of view. Believing that the murderer has been brought to justice, SHIU-GAT goes to pay respect to her late mother, where she coincidently meets YUEN-SUM, who is on her way for deity worship. In response to YAT-FEI's accusation of him having an affair, CHUN-PING lies to her, saying that he was just working overnight. With YAT-FEI successfully stopping a girl from committing suicide by using her own life experience as an example, SHIU-GAT learns that YAT-FEI's family issue has also been bothering her, so she shows her SIU-WAN's photo, hoping to encourage her. Once again, SHIU-GAT examines the evidence and prepares for the court. Suddenly, she notices there is an earring which does not belong to SHIU-LAN.… ...
