L.A. Law (or Law Lik Ah) is a noted barrister in Hong Kong’s legal circle. However, 7 years ago, he disappears from the legal circle. L.A. Law used to practice law for the fame and glory it brings but soon realises that everyone is entitled to equal legal representation. As such, together with his cousin, George Mike Jr., and best friend, Ting Ka Fu, L.A. Law sets up a legal practice in Sham Sui Po. Soon, L.A. Law becomes a “people’s hero” in Sham Sui Po as he helpes the neighbours fight for their rights and injustice with unconventional tactics. Upcoming Barrister, Wong Sze Fu, used to admire and look up to L.A. Law for his invincible performances in court. However upon learning of his present situation, she starts to disregard him for turning himself into a ghetto lawyer. Sze Fu’s impression of L.A. Law changes when she have to work with him on several legal cases and the two eventually falls in love. Sze Fu still maintains her dream of becoming a elite barrister. To advance in her career, she takes every opportunity to get close to renowned barrister, Cheung Pak Kei. Unknown to her, Barrister Cheung enjoys getting people into trouble and Sze Fu is no exception. Not long after, Sze Fu finds herself embroiled in a lawsuit. Having no other option, L.A. Law has to challenge the law to save her.
