Helen McCrory stars in this six-part ITV crime drama. The series follows human rights lawyer Emma Banville (McCrory) as she tries to overturn the conviction of killer Kevin Russell (Sam Swainsbury). Russell was convicted of murdering a 15-year-old schoolgirl but after serving 14 years of his sentence he still adamantly maintains his innocence. As Emma begins her investigations into the original case, led by DCS Olivia Greenwood (Wunmi Mosaku), she is immediately met with a negative backlash from the public and press who wish to keep Russell behind bars. As she delves deeper into the case and stumbles upon a possible conspiracy, Emma finds her own personal life under the spotlight, as she prepares to adopt a child with her husband and cares for her elderly father as his health begins to wane.
