Plot
Raymond Lau (Andy Lau) grew up in an orphanage. He is an honors graduate from the University of London School of Law, specializing in criminal law, who just obtained a law license and is returning to Hong Kong for his career. Raymond's fiancée's family also has a background in law. At this time a case occurred, an over 50-year-old prostitute Lau Wai Lan (Deanie Ip) is suspected of killing the son of a dignitary rich client. No one is willing to defend her, and she wants to die. People are not optimistic that the work ethic and sense of justice is still driving. Raymond Lau took over the case.

Rookie lawyer Raymond, through Old Kwan's (Lau Siu Ming) help, searches for evidence everywhere — the truth gradually unraveling the case. He is opposed by the father of his fiancée, and the relationship with his fiancée gradually goes down. In an accident, Wai Lan saw Raymond has a pocket watch with "bright future"  engraved on it, a gift that she gave her son many years back. She finds out Raymond was her son whom she took to Dean Maria's orphanage. Wai Lan has not abandoned Raymond: She became a dancer, anonymously cared for Raymond, and paid for his tuition and summons for the University of London School of Law. Wan Lan worried about the exposure of her identity would ruin Raymond's honor and identity; she refused to let Raymond defend her.

Raymond cannot accept that Wai Lan refused his defense. Wai Lan does not say anything but, under the persuasion of Old Kwan, Wai Lan finally agreed to let Raymond defend her. Raymond's logic clearly refutes, points out the contradiction of the allegations of witness, and the inference that the deceased is a sexual pervert. Raymond finds victims of sexual abuse — prostitutes — to testify based and looked for the victim's psychiatrist who testified. The psychiatrist, however, denied that the victim is his patient. Fortunately, one of Raymond's orphanage mates, Tang Siu Fan, who is a nurse of the clinic, agrees to testify and comes up with the medical records evidence that the victim is indeed his patient.

Prosecutor (Paul Chun) summoned Maria, the retired orphanage director, to testify in court about Wai Lan and Raymond's mother and son relationship. According to the British statutes and regulations there shall not have such kinship between lawyer and client, asking the judge to immediately revoke the litigation. However, Mary firmly denies Wai Lan and Raymond's mother and son relationship. The consent of the jury, the judge ruled that Wai Lan was harassed by her client and killed him under self-defense. At the end, Raymond still does not know that Wai Lan is his birth mother.
