Season 1

Emma Banville, a human rights lawyer known for defending lost causes, sets out to prove the innocence of Kevin Russell, who was convicted for the murder of a school girl 14 years earlier.

Kevin faces abuse from the public as Emma takes drastic measures to get the case back on track. Miriam makes a call that has devastating consequences for Emma.

As Kevin's retrial begins, Emma has a breakthrough with new evidence, but powers outside of her control seem set to crush her attempts to prove Kevin's innocence.

As Kevin's trial continues, the forensics seem to be proving his innocence and leading to an acquittal after 14 years. However, when the prosecution delivers a counter argument, Emma's hopes of a ‘Not Guilty' verdict are dashed. With Heather and Sir Alastair keen to bring the case to a close, will Kevin accept a plea of manslaughter to secure his freedom? Meanwhile, Yusef sends word that he is in the UK and wants to meet with Emma. She travels to Birmingham to see him, tracked by Olivia Greenwood who is determined to uncover Yusef's whereabouts. With Greenwood withholding vital information that Emma needs about Tony Pullings' whereabouts and Emma refusing to disclose Yusef's hiding place, the pair are at a stalemate.

Locked up in America by the US air force, Emma makes the breakthrough she desperately needs, and with help from an unexpected source, she edges closer to finding out the truth.
