Maxine Peake and Rupert Penry-Jones return in Peter Moffat's thrilling legal drama about the lives, loves and hard cases facing a group of top end barristers. Martha Costello is a brilliant, passionate defense barrister. She's also now a member of the Queen's Council - a QC, which means the stakes are always high. Meanwhile in chambers Billy's way of dealing with tough times is to tout for work from solicitor Micky Joy - a man with a reputation for representing some very heavy criminals. And 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. Is it possible that their feelings for each other could finally lead somewhere or is Clive the one person she should never trust?
