This sharp, witty legal drama about the lives, loves and tough cases facing a group of top London barristers returns for a second season. Hard working and dedicated, Martha Costello has a reputation for defending the poor and downtrodden, firmly believing all are innocent until proven guilty. Now that she's a member of the Queen's Counsel - a QC - the stakes are even higher. In the loneliness of reaching the top of her profession, Martha's love/hate relationship with Clive seems to be growing more important to her. Could their feelings for each other finally lead somewhere or is Clive the one person she should never trust?
