The Unwritten Law 1985

Andy Lau plays Raymond Lau, an orphan who grew up in an orphanage and earned honors from the University of London School of Law, specializing in criminal law, and who has just obtained his law license to practice in Hong Kong. He returns home to launch his career, with his fiancée’s legally minded circle watching his every move. A high-stakes case soon lands on his desk, centering on Lau Wai Lan, a woman said to be over fifty and working as a prostitute, who stands accused of killing the son of a wealthy client. With no one eager to defend her, she longs for death, and the case tests Raymond’s own sense of justice and his budding work ethic.

Lau Wai Lan, Deanie Yip Tak-Han, is the central defendant. The tension mounts as Raymond takes on her defense, navigating a system that seems ready to abandon her. Raymond’s resolve is further challenged when he faces opposition from the fiancé’s father, and the strain of that family tension begins to affect his personal relationship.

Old Kwan helps Raymond dig for evidence, pushing past initial assumptions as the truth slowly starts to emerge. Raymond’s growing determination clashes with the expectations of those around him, including the expectations tied to his fiancée and her family. The case becomes not just a test of legal skill but a test of character and loyalty.

During the investigation, Wai Lan makes a startling discovery connected to Raymond’s past. She recognizes a pocket watch engraved with the words “bright future”, a keepsake she once gave to her son many years ago. This revelation hints at a hidden history: Wai Lan had not abandoned Raymond. She had placed him in Dean Maria’s orphanage years earlier to protect his future, all while secretly supporting his education and well-being by working as a dancer and funding his studies. Her concern about exposing her true identity is a careful shield to preserve Raymond’s honor and reputation, complicating her willingness to let him defend her.

Eventually, Wai Lan agrees to let Raymond defend her, though her consent comes with the weight of secrecy and the fear of ruin to his name. The defense strategy hinges on dismantling the testimony of witnesses who allege various aspects of the case, and Raymond searches for the vulnerabilities in the prosecution’s narrative.

Raymond’s investigation leads to the testimony of victims of sexual abuse—prostitutes—whose accounts are scrutinized to establish context and credibility. He also pursues the victim’s psychiatrist for testimony, only to learn that the psychiatrist denies treating the specific victim. A crucial turn comes from Tang Siu Fan, a nurse at the clinic who testifies and provides medical records that corroborate the victim’s status as a patient, supplying a vital link in Raymond’s challenge to the prosecution’s claims. The defense benefits from these detailed records and testimonies as the case begins to tilt in its favor.

On the prosecution side, Paul Chun Pui steps forward as the Prosecutor and calls Maria, the retired orphanage director, to testify about Wai Lan and Raymond’s supposed mother-and-son relationship. The courtroom grapples with whether such kinship should disqualify Raymond from representing Wai Lan under British legal norms, and the judge must weigh this against the facts presented. Maria’s testimony, and the broader implications of the kinship question, create a tense atmosphere as legal arguments unfold.

In the end, the jury’s verdict and the judge’s ruling hinge on interpretations of self-defense and the pressures facing Wai Lan as she faced her client’s actions. The judge ultimately accepts that Wai Lan acted under a perceived threat, and the case concludes with a finding of self-defense. Yet the emotional and moral consequences linger, because Raymond still does not know that Wai Lan is his birth mother.

• The film maintains a steady, neutral tone as it threads courtroom drama with personal revelation, inviting viewers to consider how duty, memory, and the hidden ties of family can complicate justice.
