Shetland: Blue Lightning - Part One

SINOSSI

The first episode of the final two-part story. A scientist is found dead in the bird observatory on Fair Isle, Perez's childhood home, so he takes Tosh and makes his way across to the island, where he is greeted by his father - just before flights are grounded by incoming storms. Working alone and without a forensic team, the detectives talk to the victim's friends, family and colleagues - and as tensions run high, the storm compels Perez and the suspects to remain together under a single roof. Douglas Henshall and Alison O'Donnell star, with John Lynch and Bill Paterson.
