Leeds policewoman Jo Gillespie (Sheridan Smith) is shocked to the core when her husband, undercover policeman Ryan (Kenny Doughty), is killed in suspicious circumstances. The nature of the top secret operation he was working on when he died also means that a full investigation into his murder is obstructed by police chiefs DCI Will Hepburn (Douglas Henshall) and Chief Constable Carolyn Jarecki (Geraldine James). What begins as a painful murder enquiry for Ryan’s friends and colleagues uncovers some terrible secrets for Jo and her family. With the help of friend and colleague Jack Clark (Matthew McNulty) Jo is determined to find out the truth about her husband’s death.

Written by Matt Charman (Our Zoo) and directed by Michael Samuels (The Fear, Any Human Heart), Black Work is a powerful crime thriller that, over three hours, takes the audience into the depths of the undercover police and its inner workings, and tells the story of one woman who is determined to risk everything to protect her family.
