Eight puzzling murder cases keep good-natured Detective Inspector Jimmy Perez (Douglas Henshall, Primeval) busy -- and keep you guessing -- in the breathtakingly beautiful Shetland Islands. Among the mysteries Perez is confronted with are a local recluse who looks like the obvious suspect in the murder of a teenage girl until another corpse and a secret hiding place reveal new clues; a journalist's fatal car accident seems suspicious after Perez discovers the driver was researching plans for a controversial new gas pipeline; and a scientist's mysterious death. As Perez and the viewer quickly come to realize, not all is what it seems in this close-knit island community.
