Clive is in the city of Oxford to prosecute three male students who have been accused of sexually assaulting a young waitress. The three silks up against him attempt to use who playground tactics to beat him. Clive starts to lose his nerve but following a chance encounter with former friend Ed Marmor his confidence improves and he discovers a passion for prosecuting which he didn't know he had. Martha is defending Ricky Armitage, who has wrecked his local mini-mart and attacked the owner.

Martha is faced with challenging cases and surprising clients. Her beliefs and prejudices, her conscience and her faith in the criminal justice system are tested to the limit over the course of the series.
Joining Martha is Clive Reader. He's funny, gifted and dangerous. The same age as Martha, they're called to the bar together. Both are applying for silk - how they perform in court is vital to this process and Clive knows how to play the game.
