Academy Award-winner Kate Winslet plays Mare Sheehan, a small-town Pennsylvania detective who investigates a local murder as life crumbles around her. From creator and writer Brad Ingelsby, with all episodes directed by Craig Zobel, the seven-part limited series is an exploration into the dark side of a close community and an authentic examination of how family and past tragedies can define our present.

DI Annika Strandhed, the speedboat-driving head of Glasgow's newly-formed Marine Homicide Unit, juggles baffling cases and a rebellious teenage daughter. Joined by DS Michael McAndrews, Annika's old colleague; DC Blair Ferguson, the forensic brains behind the unit; and DS Tyrone Clarke, the new cop at the station.
