律师康芷欣（杨怡 饰）出身法律世家，做事重原则、敢言敢行。而在同一间事务所的另一位大状刘思杰（ 陈展鹏 饰）却是截然不同的作风，做事不拘小节，有时为了伸张正义，甚至不惜踩线。刘思杰的好友卓少谦（黄浩然 饰）家庭富有，为人重义气，做事散漫，做律师的初衷不过是为了一个光鲜的职业。还有正义憨厚的韦文瀚（阮兆祥 饰）、不谙世事的见习律师潘巧如（唐诗咏 饰）、精灵事故的事务律师毛敬业（黎诺懿 饰）……这些来自不同阶层的人在一起，遇到许多棘手的案件——弑父案、强奸案、杀警案、买凶案等，真相是什么？是不是真有非黑即白的世界？

Does every verdict reveal the truth? Inescapably, the attorneys in this procedural legal television drama, of varied personalities, tell their own story in the legal proceedings of the complicated cases that bring them together. Barrister Keith Lau’s ambition knows no limits. He would do everything he could in order to win a case, even if it means putting himself at risk. His good friend Wallace Cheuk runs a law firm, but has no court experience, until Mavis Hong joins his firm. Their good friend James Wai is a down-on-his-luck lawyer who is financially dependent on his mother: but when a thorny case comes his way, it looks as if his luck has finally changed.
