Meanwhile, Tosh uncovers the missing student’s online posts about deep-sea dump sites – old munitions, cold war wreckage – and a local councillor who greenlit a private survey company’s “environmental study.”

Night. A small creel boat, Aurora , rocks against a concrete pier in Whalsay. No lights. No hail on marine radio. At dawn, harbourmaster finds the skipper, Callum Williamson, slumped over a pot of tea in the wheelhouse – dead. No obvious wound. No water in lungs. Just a single, deep scratch on his wedding ring and a torn page from a tide table clenched in his fist.

The Tides That Bind Shetland S07E02 (x265 – lean, sharp, every frame counting)

No scene is extra. Every pixel tells the story. x265.

DI Ruth Calder (back on loan from Police Scotland) and DS Alison “Tosh” McIntosh are already stretched thin. A missing Norwegian student, a stolen boat from Lerwick, and now a quiet murder in a community that whispers but never speaks.

Calder stares at the Shetland horizon. Tosh brings her coffee. “You think she was wrong?” “No,” Calder says. “I think she was too right, too late.” They watch the Aurora being hauled onto a lorry, its nameplate already fading. In the last shot: the Norwegian student’s backpack, still missing, floating somewhere north of Muckle Flugga.

The x265 efficiency mirrors the episode’s storytelling: no wasted scenes. Every glance, every cut between the grey sea and a flickering pub television carries weight.

In a disused salmon farm, Calder corners the killer: a widowed mother whose son was the “drowned” man from ’09. The son had tried to expose the council’s toxic dumping. Callum and the others swore a false report. She’s been unpicking the lie, one thread at a time – the student was an innocent witness. Now the tide has turned.
