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...
