A crime which Kevin maintains he didn’t commit.

Firmly believing there has been a miscarriage of justice, Emma is determined to reveal the truth behind Linda’s death and is prepared to go to extreme lengths to discover what happened and free Kevin. However, as Emma digs deeper into the case, risking her career, personal life and reputation, she begins to sense powerful forces at play within the police and intelligence services who want to stop her uncovering the truth.
