Created and written by Kate Brooke (Mr Selfridge, Ice Cream Girls, The Making of a Lady), leading actress Sarah Parish (Broadchurch, W1A, Cutting It) plays respected police officer Detective Superintendent Elizabeth Bancroft. Ruthless and courageous, Bancroft is a brilliant copper. She has given her life to the police force. But when ambitious fast-tracked recruit Katherine Stevens joins the force, played by acclaimed actress Faye Marsay (Game of Thrones, Black Mirror, Love Nina), Katherine takes on a cold case and unwittingly disturbs the ghosts of Bancroft's devastating past. With strong female characters at its heart and a detective with an explosive secret, this original crime drama is packed full of twists.
