This new four-part police drama with an impressive cast is about a young officer living a double life. DS Nancy Devlin (Karla Crome) is a great copper, except she has been keeping Frank (Philip Glenister) – her best friend’s dad – out of trouble for years, making sure his name is never linked to a crime.

When he calls her one dark night, events take a turn for the worse and Nancy is thrown into an impossible situation of investigating a case that she is secretly at the heart of.

Can she keep her colleagues in the dark, while protecting herself and Frank’s family? Also starring Amanda Burton, Doctor Who’s Noel Clarke, Laura Haddock and Downton Abbey’s Rob James-Collier.
