Originally created from award-winning writer Ann Cleeves' bestselling novels, gripping crime series Shetland returns to find DI Jimmy Perez (Douglas Henshall) facing murders from the past and present with unsettling similarities in this new single mystery.

When Shetlander, Thomas Malone, has his conviction for the murder of teenager Lizzie Kilmuir overturned after 23 years behind bars, Perez must reopen the investigation. Many in the close-knit island community still believe Malone to be guilty, so when his return coincides with the murder of a local journalist, he's very firmly in the frame. As both cases become increasingly complex, stretching to Norway and into the murky world of far right extremist groups, Perez is pushed to the limit both professionally and personally. He's as determined as ever not to give up, but, as he closes in on the truth, the investigation will lead him closer to home than he could ever have imagined.
