这里汇聚了各种律师，他们各具本领，各显神通。Martha Costello（玛辛·佩克 Maxine Peake 饰）是一个三十多岁，单身，但依旧富于激情的辩护律师，准备申请皇家律师资格。Martha面临着极具挑战的案件以及令她惊讶的客户。她的信念、她的偏见、她的良知以及她的信仰的极限在刑事司法系统中被一系列的课程所检验。Clive Reader（鲁伯特·潘瑞-琼斯 Rupert Penry-Jones 饰）和Martha年龄相同。但他为人风趣，有天赋但同时也很精明。两人同时都是律师，同时都申请了皇家律师资格，在庭上的表现直接影响他们的命运，而Clive知道如何来玩这场游戏......
究竟谁最后能成为皇家律师呢?

Whilst Clive Reader celebrates his taking silk but Martha hits the bottle, angry that inspector Wright has lied in court to convict her client Johnny Foster. Later David, the teen-aged son of chambers head Alan Cowdrey, is arrested for causing the death of a policeman , one of six who kettled him during a demonstration. Martha believes David has been bullied into pleading guilty by Wright and wants Alan involved in his son's case but David is not keen to see his father. Reader and Caroline Warwick agree to help Martha, who sees on CCTV that an anonymous man spoke to David in custody but there is no record of this meeting. In court she faces Wright, this time determined to beat him but evidence comes to light which weakens Martha's crusade.

Martha is at last a QC,making her senior to Reader. Their first case together is defending taciturn thug Brendan Kay,muscle for the infamous criminal Farr family,accused of half-blinding a motorist who fell foul of boss Jody Farr. Martha believes Farr's influential solicitor,sharp Micky Joy and Farr are conspiring to stitch up the innocent Kay for a crime Farr committed. Battling against both formidable prosecutor Caroline Warwick and head of chambers Alan Cowdrey for Farr,Martha finds that Reader proves to be an ultimate help to her. He also has a solo case, defending killer Fatima Ali,referred by female solicitor George Duggan,who resists his efforts to pursue her romantically.
