Starring Anne-Marie Duff, this psychological crime drama sees a former policewoman forced to face her dark, guilt-ridden past.

Duff, who is best-known for playing Fiona Gallagher in TV series Shameless, leads the cast in the role of Claire Church, who is living on a remote Scottish island with her partner and daughter. A former colleague from Manchester convinces her to come to the city to investigate the mysterious deaths of a number of prostitutes, as the case seems attached to one Claire worked on seventeen years prior.

The BBC series has been compared to The Fall and Happy Valley in its portrayal of a tough female cop.
