MAN (CHIT’s elder sister) is a retired singer. She has married a millionaire, CHIU. They have a daughter, TONG. However, CHIU is born very suspicious. He always suspects TONG who is not his flesh and blood child. Thus, he is very cool to TONG. MAN’s old lover, CHOR, backs to Hong Kong from overseas. He wants to recover the old relation with MAN. It soon becomes the hot-gossiping issue of the press. MAN and TONG quarrel with each other. MAN and her mother, KUEN, set a plot to kidnap TONG. They aim to test CHIU and see how much does CHIU love TONG. Unexpectedly, TONG is really being kidnapped. The kidnapper asks for over thirty million ransom. YUEN (CHIU’s younger brother) manages his business in Indonesia. In fact, he is always controlled by CHIU. He always tries to convince him selling his share to his girlfriend’s father but is in vain. Time is tight. CHIU has no other alternative.… ...

CHIU hands the ransom to the kidnappers by himself. He has not yet backed. FAI was being charged of destroying CHIU’s property two days ago. It is because FAI's wife and daughter was died of accident at CHIU’s site. However, he does not receive any reasonable compensation. CHIU does not show up to the police station to identify the criminal. YUNG then goes to CHIU’s home and discovers the kidnapping case. YUNG and YUEN hurry to the empty flat to find CHIU. They find that CHIU was dead and the ransom lost. The coroner's report shows that CHIU was chopped to death. FAI is the major suspect. The police finds out that FAI is actually not the real murderer. FAI met an car accident when the murder case was happening. He has became insane after the car crash.

YUNG persuades MAN to disclose the case to the public and set up a hotline to receive more information. He even plans to have money reward for any information provided for clearing up the case.Soon there is some news form a citizen. This citizen states that he witness CHOR who let the spot secretly with bloodstain. The police checks CHOR’s record and find out the he is a retired singer. He has become bankrupt and has got divorce. He then backed to Hong Kong. The police installs a voice detector at CHOR's hotel room. They watch him closely. They find that he always dates MAN. The police then send some cops to watch MAN. Soon they discover that CHOR arranges MAN to meet TONG at Cheung Chau. The police follows them to Cheung Chau. The cops eventually find CHOR’s dead body after encountering a lot of difficulties.

The flat was sealed for inspection. They find some smoked cigarette filters, some long hair, TONG’s bracelet and an ear-ring. The hair and ear-ring are belonged to MAN. MAN is interrogated. She gives testimony stating that CHOR will only release TONG with the condition that she left Hong Kong . YUEN is the only person who knew the case. She goes to Cheung Chau to pick TONG up according to CHOR’s instruction. However, she waits for a long time and cannot meet them. The police checks YUEN’s background and finds that he is an illegitimate child. Thus, he only receives one-ten of the family property and wealth. YUEN could inherit all family property and wealth if CHIU died. The brand of the cigarette filter at the spot also matches with YUEN's used brand. Soon YUEN's girlfriend, NEI, reports to the police and asks for protection. She unveils the truth. She had helped YUEN to kidnap TONG. Later, she found that CHOR was dead.… ...

NEl also tells that TONG has already fainted at her home. The police hurries to the spot to save TONG. Simultaneously, CHIT suspects YUEN. She slips into his flat and check for NEI’s address at his telephone book. She then hurried to NEI’s flat. YUEN also suspects CHIT who has had checked NEI's address at his flat. Thus, he also hurries to NEI's flat with the aim to kill TONG so as to cover the truth. YUEN brings TONG away with him. The police eventually arrests YUEN after a fierce chase. However, he does not tell the police TONG’ location. The police discloses the nevus to the public. MAN implores YUEN to tell her TONG’s whereabouts. YUEN refuses. However, YUEN is filled with remorse. In order to satisfy his conscience, he tells them that TONG is hidden in a container. YUNG could eventually rescue TONG who is nearly died.

Three cases of rape-and-murder have occurred recently. The three victim were strangled to death by the killer and neither finger- prints nor sperms can be found. The police force set up a special team to handle the case. MAN is transferred to YUNG's team to give him a helping hand. YI also returns after his vacation. YUNG finds that the three victims uses the perfume “Envy”. It has special scent and is not popular. Few customers use it. Incidentally YUNG discovers that CHIT's uncle WAI had taken photographs of the three victims in his studio before the tragedies occurred. WAI is suspected. They keep an eye on WAI and finds that he courts DAISY. They go to a hotel and after thirty minutes. the girl screams for help.

It is find that WAI and DAISY quarrel as they cannot compromise with the price involved in the filthy transaction. YUNG also finds that WAI's behavior is different from that of the murderer. However a witness recognizes that WAI was with the third victim before being killed. WAI admits that that night he escorted her home but after that he returned to his studio. As there is no one proving' WAI's statement, he cannot prove that he is innocent. WAI’s counsel KIT and four waiters claim that WEI was in the coffee shop of a hotel and he wore an orange jacket. As the jacket has been sent to a laundry, KIT's statement is not accepted. In fact WRI tries to hide the truth as his filthy relationship with the owner of the hotel may be disclosed. The fourth case occurs and ADA is the victim. Luckily ADA regains her consciousness.

ADA reports that she was attacked by the sex maniac from behind and she fainted. YUNG gets an idea and they narrow down their scope of investigation to doctors and YUNG- finds that doctors have more chances to be close to their patients. After checking it is discovered that all the four victims were clients of St. Peter's Clinic. SUT, MING and CHAI are suspected as they' are doctors there. MAN is instructed to go to the clinic to bait the real murderer with “Envy”. She takes refuge in a unit being protected by the police. The killer arrives but is frightened by the alarm of the life which is out of order. YUNG sees the car of the villain and they focus on SUT and CHAI as they have the car of the similar style. It is found that SUT had bought a bottle of “Envy” near MAN’s unit and then he disappeared. It is rather certain that SUT is the sex maniac as the four victims’ records are found in his house.… ...

However medical checking shows that SUT had been poisoned to a comatose state before being killed in the traffic accident. Moreover there is no finger-print on the steering wheel. It is certain that it is a set up murder. YUNG and YI rush to save MAN but it is too late. MAN has been kidnapped by CHAI. Seeing that he has been surrounded, CHAI releases MAN and goes to the roof, trying to kill himself. CHAI committed the cases as he was shocked by his wife who had betrayed him. The situation worsened as he found that his son was not his flesh and blood. His anger explodes when he met the victims with “Envy”. His wife had a gift of “Envy” from her secret lover. He went insane and calmed himself by killing the victims. When he knew that he was suspected, he used tricks to frame SUT but in vain. He has to face trial by the law.

In a used car lot, a corpse is found. It has been burnt seriously. The only hints about the identity are the feminine gender and the letters “TL” on her necklace. FUNG asks the public to supply useful information through the mass media. The next morning a teacher working in an evening institute. The identity of the corpse is clarified. She is LAI and has disappeared for three days. On the other hand, the press receives information from CHING who tells the press that LAI killed her daughter in a traffic accident one year ago. YUNG goes to ask CHING but cannot find her. He suspects that LAI was killed by CHING who wanted to avenge her daughter's death. More background of LAI is disclosed. Before working as a teacher in the evening institute, LAI worked as CHEUNG's secretary. She was dismissed by CHEUNG's wife who was discontented with the intimate relationship between CHEUNG and LAI.… ...

FUNG does not agree with YUNG. She refuses to continue the investigation as it is a waste of time and resources of the police. CHIT uses YUNG's idea as the main theme of her novel. She realizes that if YUNG is correct, LAI's situation is dangerous as she may be killed by CHEUNG who wants to keep his secret. Meanwhile the police find LAI and CHEUNG in a flat. CHEUNG is dead. LAI is sent to the hospital. When she regains her consciousness, she reports that CHEUNG attacked her so as to keep his secret. It happened as YUNG suggested. However it is found that CHEUNG was not killed by a knife. Instead he was poisoned. CHEUNG's wife declares that she killed CHEUNG with pesticide as she knew that CHEUNG was not loyal to her. The case is solved.

YI and CHI go to Japan to enjoy their holiday. Before getting abroad, YI meets HO whom is believed to have died for five years. YI delays his trip to find what has happened. YI and HO lived in the same walled village. HO left her home as she was forced to marry a man that she did not love. She went overseas to study design. SAN was HO's boyfriend. The police questioned him and suspected that HO had been killed by SAN as some blood stints were found on his jacket. SAN admitted that he had been in HO's house. Though he was suspected, the police did not have strong evident to prove him guilty. SAN was set free. Later SAN killed himself and left a letter stating that he felt guilty. YI checks the file of HO's case. He is shocked to see that SAN cannot kill himself with the rope as he used his left him. YI suspects that it is a homicide.

YI visits FUK, who is SAN's father. It is too late as he has died for two days. The way of handling the rope is the same as SAN’s. FUK has no reason to kill himself. There are a Double-T ticket and a map in his pocket. With the help of the map, the police find BILL's corpse. BILL is a wanted criminal who committed a bank robbery five years ago. He was killed but the money is not with him. As BILL and HO have the same blood type, thus five years ago, BILL was killed instead of HO. It is clear that the one who has taken the money is the killer. SAI, CHOI and KEUNG are suspected as they became rich in the past five years. MAN returns to FUK's house and a needle is found. She realizes that FUK was paralyzed and became unconscious before being killed. They check FUK corpse and MAN's idea is proven.

KEUNG is the only one who knows Chinese medicine and the use of needles. YI is aware of the unnatural response of KEUNG's wife PING. He follows her and finds HO being locked up in a deserted warehouse. PING is going to deliver a baby. YUNG sends her to hospital and tries to contact KEUNG. He cannot find KEUNG as KEUNG has gone to Devil Hill with YI. YI and KEUNG are good brothers. YI tries to convince KEUNG to surrender himself to the police. He does not know that his life is endangered. SAI, CHOI and TSUI are KEUNG's colleagues. They try to kill YI. YUNG comes and fires his gun. TSUI is so afraid that her gun hurts SAI. She and KEUNG run away. KEUNG is arrested. He goes to the hospital and he finds that his wife is safe. He tells the police everything about the case. SAI dies as he has been injured seriously. TSUI kills herself as she feels guilty. CHOI is arrested.

YI checks the CHIUs. The eldest son of the family has died and his wife controls the fortune of the family. The second son is discontented with his sister-in-law. However he is not a talented man. He only enjoys his life. As the second son is in financial difficulties as he indulges in gambling. The second son is suspected. The criminal calls the second son and asks him to tell the others the arrangement of giving money. The police suspect the second son. However the criminal does not come as stated. The criminal calls again and the phone is received by the branch manager. The second son may not be the criminal. Suddenly the criminal arrives in a car at high speed. He takes the money away. The police follows him.

KAN's prediction is wrong and thus the criminal manages to escape. Luckily CHUN is saved. The police view the video tape over and over again and at last it is recognized that the criminal is TUNG who was a policeman. He was arrested by KAN and was dismissed as he had stolen the money robbed from a bank. YUNG follows TUNG's elder sister to the flat where TUNG stays. However he has left. TUNG's sister tells YUNG that she was given two hundred thousand dollars by TUNG. TUNG told her that he had won Mark Six. After checking it is proven that the money belongs to the CHIUs. YUNG and KAN want to arrest TUNG. KAN is so quick-tempered that he guns down TUNG.

Incidentally YUNG finds a boy's shoe in KAN's house and it is of the same pair of another one being found in TUNG's house. KAN knows that his secret is discovered and admits that he is involved in the case. TUNG kidnapped KAN's son to take vengeance on KAN. KAN kidnapped CHUN so as to get the money to save his son. A corpse is found in a construction site. WING checks it and finds that the man died six or seven years ago. He has six fingers and wounds are found on his bones. YUNG seeks help from HIN. With computer technology, HIN rebuilds the dead man's appearance so as to identify him.

However HIN’s method cannot be employed as a piece of acceptable evident in the court. The model is lost on its way back to Hong Kong from the United Kingdom. YUNG takes the draft and asks the people living near the construction site. At last it is recognized by BING who owns a store. She recognizes him as LEUNG and he was LAN's boyfriend. It was said that he had gone to Singapore. KUEN is LAN's friend. LAN has a son and a daughter. LAN always quarrel with WING. She asks KUEN to keep an iron box for her as she is afraid that WING may dispose of it. The police visit LAN. LAN is shocked to learn that LEUNG is dead. WING is also shocked and he asks the police to leave.

LAN uses town gas to kill herself. Though she is saved, she is in a deep comatose and has little chance to wake up. As LAN’s keys are lost, YUNG suspects that LAN was murdered instead of committing suicide. He also finds that WING tries to find something in LAN's house. KUEN gives the ox to the police. It contains a letter and a photograph stating that WING was all right in Singapore. However it is found that the letter was written by WING. The lost model is found in WING's house. The police also discover that WING makes frequent donations to St. Maria's Church. WING is questioned but no further information can be obtained. He is set free. The police keep an eye on WING and find that WING asks his girlfriend YAN to take money and flowers to the church. Suddenly WING reports to the police that he was the killer of LEUNG and LAN. He did so as he hated LEUNG who wanted-to take the role of his father.… ...

LAN regains her consciousness. She tells YUNG that WING did not hurt her. That day BING visited her and questioned her. BING was LEUNG's intimate girlfriend and she was angry as LAN had killed LEUNG. In chaos BING pushed LAN to the floor and LAN fainted. BING is questioned but she refuses to admit. At last WING claims that he is the witness and BING admits that she hurt LAN. However WING is still accused of having killed LEUNG. MAN finds that WING's sister WAI lives in the church. WAI became crazy after being raped by LEUNG. Her condition has improved and she admits that she killed LEUNG. Now she realizes that if she want to forget the unpleasant experience, she must confront the reality before the God. WAI is not accused with YUNG's assistance. WING is happy to see this arrangement and he marries YAN. He and his family turns a new page of life.

WA is a magazine journalist. His corpse is found in the woodland near Butterfly Stream. He was hit with hard objects and died for losing too much blood. There are many mysterious points about his death. His house had been searched by unknown persons after his death but his money was not taken away. Moreover it is found that over one million dollars has been deposited in his account. The police suspects that WA was killed as he wanted to disclose some scandals. As WA was dealing with LING, who is a singer, LI, FUNG and MIN, who are actresses, they become the targets of investigation. FUNG invites MIN and LI to act in a film invested by her. FUNG and MIN have announced their engagement. LI falls down from a ladder in the studio and dies.

It is realized that LI is not involved in WA's case. She needed money not because of being threatened by WA, instead she used the money to help her brother. As the screws had been loosened before she fell from the ladder, it is clear that she was murdered. YI thinks that it is only a joke instead of manipulated homicide. FUNG and. MIN have announced their engagement and the ceremony takes place in FUNG's house. However FUNG announces it is only a gag. He will not marry MIN. MIN feels being fooled. She is discontented as FUNG has another lover. She is on the brink of collapse but she still promises to act in the film. She tells the journalist that she wants to avenge her being humiliated. When they are acting, MIN shots FUNG with a real gun. FUNG dies and the others are shocked.

MIN is arrested. In MIN's car, YUNG finds the forgery gun. Most likely she has left it in her car and she wants to destroy it. At the same time, an informant reports that the gun was sold by a drugs smuggler to a girl looking like MIN. MIN is accused of committing homicide. The police starts questioning FUNG's previous lovers. They are surprised to know that all the “lovers” are gags of the film making company. All the “lovers” state that FUNG is a good man.

The case becomes more complex as the solicitor announces that FUNG wants to give one-sixth of his fortune to his manager SAU and one-half to his lover MIN. After consideration, the police figure out that LI died for MIN as MAN should be the one on the ladder. Thus the one being threatened may be FUNG. A camera is found in FUNG's house. The film is finished and the photographs are shocking. MIN goes to FUNG’s house where she sees SAU putting on dresses. In fact FUNG and SAU are lovers. Their abnormal love was found by WA who blackmailed them. SAU killed WA to keep the secret. Later FUNG fell in love with MIN. FUNG changed his mind where he knew that SAU had killed WA for him. However he did not want to continue the love. SAU hated MIN and wanted to set up a trap to frame MIN having killed FUNG. His plan was spoiled by the video tapes.

When SAU is going to kill MIN, the police arrive. There is a gun fight. MAN protects YUNG with her body. SAU is killed. MAN is hurt seriously. Fortunately she recovers. However her legs are paralyzed. There is only fifty percent of recovery. YUNG looks after her as his life was saved by her. However CHIT is jealous. LUN's corpse is found on the stony beach of Tai Mong Tsai. For checking it is found that LUNG had taken sleeping pills before being killed by carbon monoxide. LUN is a keen gambler and this hobby always put him in financial difficulties. His wife is PO and KWAN is his secret lover. They have witness to prove that they were not with LUN when he was killed. LUN owns a saloon. PO works in a flower shop and KWAN is a taxi dancer. Before LUN was killed, the guard of the building saw a girl in red clothes came to drive LUN away. However he could not see the girl.

LIK, who is the partner of LUN, is suspected as the killer for three reasons. Firstly, his father runs a garage and thus LIK is good at car mechanics. Secondly LIK and LUN had quarrels over financial matters. Thirdly LIK and KWAN has filthy relationship behind LUN. However LIK has witness to prove that he was not with LUN when LUN was killed. The police go to question PO's family but no useful information is found. When they are on the way back to the headquarters, they meet a truck driver. His truck's tires went flat at Sap Shi Heung when LUN was killed. He saw a girl in red clothes driving a white car and leaving in a hurry. Thus they return to the scene where they find a burnt cigarette with lip prints on it.

However the case has not been solved. LUN was taken away by the girl in red at 8:00 p.m. and she was seen at Sap Shi Heung at 9:00 p.m. At 10:15 p.m. LIN was killed at Tai Mong Tsai. YI accompanies PO and her grandmother to home from hospital. YI finds an old photograph taken when PO was a student. YI suspects PO's classmates and thus he takes the photograph away.

Before she died, BETTY called CHIT. BETTY told CHIT that she had the idea to kill the baby so as to get compensation from the insurance company. Luckily the baby is all right. CHIT also heard the music of a wind bell. CHIT recognizes that the music is the last piece in the department store. The police go to the department store and the shopkeeper recognizes BETTY and reports that she and a man came and bought the piece. CHIT finds the man but the shopkeeper firmly states that he is not the one. The man warns CHIT to mind her own business. It is found that BETTY's skin tissues was left in CHUNG's fingernails. The newspaper hawker also identifies her as the mysterious girl outside LIN's house. Thus it is clear that BETTY killed CHUNG for money. But why did she kill LIN? Moreover it is believed that BETTY did not kill herself. She was killed by the black hand who wanted to keep the secret. The man threatened CHIT is FAY.… ...

CHIT finds out who the black hand is, endangering herself. However the police do not have strong evident to accuse him. The police attempt to accuse him of three charges. Though KAI tells everything he knows, his words are not trusted as he suffers from cancer. CHIT's colleague SEE is going to marry MAN. SEE tells CHIT that she has no faith in marriage as four years ago, her sister and brother-in-law were killed by her brother-in-law's secret lover. However the court stated that it was only an accident and the killer was set free. Incidentally SEE comes across the killer RACHEL in the street. She claims that she is CARMAN but SEE insists on accusing her being RACHEL the killer. CARMAN is confused. CHIT finds that both CARMAN and RACHEL have the same surname NAM.

SEE calls CHIT and tells her that she has strong prove to support her idea. Then she does not turn up. Later her corpse is found in her house. She was suffocated by a cushion and it seems that the killer wanted to find something before he left. MAN is the suspect but his brother WING can prove that he is innocent. MAN is questioned again as he has bought an insurance policy for SEE. They have joint account and a flat. On the day when SEE was killed, he withdrew five hundred thousand dollars from the account. MAN claims that he has another witness but the witness has migrated to the USA. He cannot prove that he is not the killer. Later MAN falls down from the roof of a building and dies. It is regarded as a suicidal case as MAN feels guilty. However it is wrong as MICHAEL returns and proves that MAN did not kill SEE.

CARMAN is on the brink of collapse and she is annoyed with a nightmare relating to the murder four years-ago. She is depressed to see CHIT and YUNG being so intimate. MAGGIE returns from the United Kingdom and brings along with her some documents to prove that CARMAN did go there to study four years ago. Before MAN died, he claimed that MAGGIE could prove his words. However MAGGIE is killed and her parcel cannot be found. From the computer of the police force, CARMAN finds that she went to the United Kingdom to further her study four years ago. She had never been to the hospital like what her brother stated. In fact the hospital does not have her record. It is certain that CARMAN has lost her memory. CARMAN gradually regains her memory about the fire four years ago. CARMAN quits her job and agrees to leave with her brother.

However it is a trick. After her brother has gone, CARMAN starts her plan of killing YUNG and CHIT. She wants to kill them with fire and the same tragedy occurs. Luckily it is stopped by YI and CHI. CARMAN is arrested and she admits all the charges. WING returns and surrenders himself to the police. He tells another story. It becomes confusing as it is hard to know who has told the truth. At last CARMAN is released. However she cannot confront her past and present. She chooses to leave Hong Kong alone. YUNG's colleagues organize a camping so as to bridge YUNG and CHIT but some unexpected incidents occur...

TO and his wife LAM have been lurked and attacked by a mysterious man three times. They are frightened and they inform the police. When it is the second time for TO to go to the police station, LAM is killed in their house. Some background information of the couple has been collected. LAM is the foster daughter of a billionaire. After the rich man's death, LAM and the rich man's son CHI had an argument in the right to inherit the fortune. The court gave LAM the right and CHI hated LAM. CHI tries to hide where he was when LAM was killed but his lie is spoiled by the employee IVY. At last he has to admit that he was with a male prostitute when the crime was committed. It proves that he is innocent and the killer is someone else.

CHI attends LAM's funeral and there she recognizes that IVY is YUNG's ex-girlfriend. She also finds TO to be someone that she should know. Later CHI is killed in a traffic accident. The police discover that TO is not as loyal to his wife as one expects. Thus TO is believed to be the killer of LAM. YUNG leads his men to TO's office to arrest him. They cannot catch him because he dies after drinking a cup of poisonous coffee. Later it is found that IVY is TO's secret lover and her car is of the same model of colour of the one that killed CHI.

As the police has no other evident to accuse IVY, FUNG detentes her for forty-eight hours so as to collect more information. when YUNG sees YAN wearing the ring given by TO, he suspects her as the real secret lover of TO. His idea is consolidated when he sees YAN expressing her hatred by tearing LAM's clothes. Moreover YAN knows driving and she has a car similar to that of IVY. When they get the information of where the car is, YUNG and YI go to arrest the killer. They are late and the car has been driven away. However they do not give up. They follow it and at last pushes it into a dead-ended alley. There they check who the driver is.

YUNG and CHIT determine their date of marriage. In order to be a good wife, CHIT attends a cooking course. In the education centre, she meets a mysterious lady who intends to attend all courses. CHIT finds a vague image of the lady in her mind. She remembers that the lady is called TUEN MUK CHI. There was a lady with the same name who committed suicide six months ago. YUNG checks the file again and learns that the victim had left a letter to CHRIS before she killed herself. According to the record, CHI lived in CHING’s house. CHING is attacked and her house has been searched. CHIT suspects that CHRIS is NAM who works as a tutor in the education centre. However NAM is killed with a knife in the show room.

The killer leaves no clue in the show room. After investigation, it is found that CHI is the daughter of WANG who runs big rubber business in Malaysia. As WANG did not accept CHI's boyfriend, CHI eloped with her boyfriend to Hong Kong. Some information of CHING and her photograph are found in NAM's house. It is because NAM has hired a private detective to check her. An employee of the education centre reports that before NAM was killed, he had had secret discussion with another tutor YUEN. Later YUEN is found killed by poison. Incidentally YUNG gets a video tape from a peeping Tom. From it the secret relationship between CHI, YUEN and NAM is exposed. They suspect that the killer is one of those in the education centre.

The real identity of SUN, who works as the school janitor in the education centre, is confirmed. He admits that he is the one who killed YUEN and NAM to avenge CHI's death. All are under his control and the plan is made up by him. It seems that the case has been solved but YUNG suspects that it is not the end as the mysterious man who attacked CHING is still unknown. Later YUNG finds that the one who attacked CHING is SUM, another tutor. However he is shot to die. As SUN has been arrested, there is another killer. YUNG suspects that the killer is CHING's boyfriend CHRIS as he knows much about the education centre. However who is CHRIS?

At last CHRIS is found. It costs so much time to find CHRIS as everyone has adopted the wrong approach to the case. CHIT gives the invitation card to her former classmate SHIRLEY. She learns that SHIRLEY has an argument with her boyfriend SHUN. As SHUN has got married, SHIRLEY urges him to make a decision in their future or she will kill him and herself. Later SHIRLEY is found having fallen down from the roof of a building and she dies. The police believe that she kills herself as she is too confused in her love affairs. In the wedding ceremony of YUNG and CHIT, CHIT is knocked down and faints. She is in a comatose.

CHIT is sent to the casualty. Senior Doctor YIN suspects that CHIT's nerve is suppressed by some abnormal cells of her brain. However treatment is difficult and dangerous. The chance to cure her with operation is low but if there is no further action, she will remain in the comatose forever. Meanwhile CHING leads another doctor BENNY to see CHIT. BENNY is an expert on brain and he discovers that the X-ray film with bad brain cells do not belong to CHIT. CHIT is still unconscious as she is under an anesthetic by an injection. Later YIN resigns and is found dead mysteriously. The police cannot find SHUN. NGAN's wife informs the police that NGAN and SHUN had been blackmailed for one million dollars before NGAN was killed. YUNG suspects that they were threatened by CHOI, who is the husband of their former patient. He did so to avenge his wife's death.

SHUN's corpse is found and a cheque of one million dollars is found in his pocket. CHOI is YUNG's former classmate. KIN tells YUNG his worry. Twenty years ago, KIN used a wire to kill CHOI's bird. As YIN and SHUN were strangled to death by a wire, KIN worries that he will be the next target. CHIT wakes up and she loses her memory. No matter how hard YUNG, tries, he is unable to make her remember him. Meanwhile YUNG discovers that YIN and SHUN were threatened by TAT instead of CHOI. TAT is the husband of another patient of YIN and SHUN. Moreover it is certain that CHOI is innocent as his dead body is found floating in the sea.

The case becomes more complex as of KIN and his wife YIN are found unconscious in KIN's car. As YIN’ has intestine cancer, poison cannot be diluted and at last she dies. KIN is cured and he discloses his plan to avenge and it involves a scandal relating to doctors...
