Martha Costello is in her thirties, single, passionate and a defence barrister applying for silk. Innocent until proven guilty are four words she lives by. But how does this fundamental principle stand up to examination by clients who are sometimes good, sometimes bad and sometimes evil?
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.
