All 12 episodes from the first two series of the BBC drama starring Sarah Lancashire as a police sergeant in a rural West Yorkshire valley. In series 1, Catherine Cawood (Lancashire) receives a visit from Kevin Weatherill (Steve Pemberton), a distressed member of the Yorkshire community she oversees, and is drawn into a ransom case in which the life of Ann Gallagher (Charlie Murphy) is at stake. Kevin employed local thug Ashley Cowgill (Joe Armstrong) to kidnap Ann in the hope of extracting a ransom from his boss, and his remorse has come too late to prevent the crime. Can Catherine get to the girl in time? In series 2, while investigating a case of sheep-stealing, Sgt Cawood discovers the decomposed body of a murdered prostitute who she later discovers is the mother of Tommy Lee Royce (James Norton). This revelation places Catherine at the centre of the investigation as a possible suspect while Royce continues to torment her from inside his cell with the help of his new accomplice Frances (Shirley Henderson). While she takes on a new case of human trafficking, Catherine deals with more complications in her personal relationships and is recommended by her bosses to undertake a course of counselling therapy.
