Defending the Guilty

Caroline and Will take on a last-minute prosecution case, only to find that the system has conspired to make it almost impossible to win.

Faced with an elderly skittish victim who just wants it all to be over, and an underfunded chaotic system that thwarts them at every turn, Caroline and Will ride their luck alongside a harassed CPS and an unhelpful volunteer, in a wacky race to bring a thug to justice.

Meanwhile the pupils' competition heats up, and Liam and Danielle find incriminating evidence against Pia. Things get figuratively and literally dirty. Will, still juggling the deceit in his personal life, wants no part of it. But, in this world, who can afford to be an idealist?

An unusual series of incidents occurs on the London underground, and Will and Caroline find themselves lumbered with representing a man involved. As they delve deeper into the case, they find him difficult to get a handle on, and struggle to decide if he is just a harmless eccentric, or something much creepier. Will takes the opportunity to get to know his mentor a little better - and soon regrets it. Meanwhile, Ashley begins making some political moves.

Chambers is putting the pupils through their paces in a professionally acted mock trial.

Liam and Danielle spend time with the actors to plan their case, only for Liam to fudge the boundaries between reality and fiction.

Meanwhile Will learns the dark art of cross-examination from Caroline - only to find it's a skill he's going to need in his personal life too.

It's the day the pupils get ‘on their feet': addressing a court for the first time. But Will is reeling from the break-up of his relationship - and wondering whether the law is really for him.
