FONG CHI-LIK, a formidable businessman, is renowned for being ruthless and quick-tempered, taking any means necessary to achieve his goals. In order to successfully acquire an old urban district and redevelop it into a sleepless city, CHI-LIK frightens Acquisitor WOON with threats over and over again. CHI-LIK's wife TONG SIN-HANG is very meticulous, taking care of things for her husband behind the scene. 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. Later on, SHIU-GAT reveals the issues of her mother to YAT-SHAN, trying to make him understand the reason why she has not agreed to marry him. Taking advantage of the police investigation, CHI-LIK puts pressure on Acquisitor WOON.… ...

CHI-LIK requests all staff to undergo a health checkup, but finds out that only few are in good health. So SIN-HANG is determined to get a suitable donor organ by any means necessary. CHUN-PING's girlfriend YAT-FEI is a postgraduate student. After learning that her parents will come to Hong Kong, CHUN-PING changes his car regardless of the enormous cost. SIN-HANG also helps receive them because she regards CHUN-PING as her own family member. SHIU-GAT joins forces with another team led by CHIU SIR to catch a lecher obsessed with long legs, during which she comes to realize that his team members have long been lazy and sluggish. She also re-encounters her primary school good friend, HA SZE-KA, in the mission. LUK YUNG borrows money from a finance company for YAT-SHAN's twin brother YUET-SHAN, but she ends up fleeing for fear of being asked to pay off the debt. As a result of carelessness, CHIU SIR falls and dies.… ...

CHI-LIK treats his subordinates really well, purchasing a luxury mansion for newly-married CHUN-PING and YAT-FEI. 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. Apart from secretly ordering an engagement ring, YAT-SHAN also invites SHIU-GAT to the beach, where he tells her some bygones so as to encourage her to walk out of the shadows. On top of that, YAT-SHAN also seizes the chance to propose to her.… ...

Notwithstanding a surgery, YAT-SHAN is pronounced brain dead, so CHI-LIK gets informed that the heart transplant operation can proceed. SHIU-GAT thinks there’s something suspicious behind YAT-SHAN’s death, so she goes to the scene to investigate it. The transplant operation completes successfully, however, due to the privacy of the donor’s identity, CHI-LIK is unable to express his gratitude for that. SIN-HANG gives a precious necklace to YAT-FEI, who instead worries about CHUN-PING. WING-YAN brings SHIU-GAT home to celebrate her father’s birthday, and her father is actually SHIU-GAT's subordinate, namely SAI-KAU. During her visit, SHIU-GAT gets to know that all her co-workers express strong dissatisfaction over her. CHI-LIK did not have a sweet tooth before his surgery, but now he often craves sweets on impulse. Ever since YAT-SHAN's death, SIN-CHI has been visiting SHIU-GAT to avoid leaving her alone.… ...
