⚡ Plot — The Frozen Heart of Lunniswick

In the isolated hamlet of Lunniswick, the body of Eadie Tulloch, a retired social worker, is found lying out in the cold — untouched for days. As Calder and Tosh begin their investigation, they quickly sense that the close-knit locals are hiding something sinister.

Eadie was a woman with a conscience, one who helped others… perhaps too much. Behind every kind face in Lunniswick lies a history of betrayal, loss, and vengeance — and when the detectives start asking questions, the village’s frozen calm begins to crack.

As Tosh and Calder piece together Eadie’s past, a shocking connection emerges — one that strikes close to home for a member of their team, pushing loyalty, duty, and morality to breaking point.

“Shetland’s always been about ghosts — this time, they’re still walking.”

🧊 A New Dynamic: Tosh & Calder

With Ashley Jensen stepping into the role of DI Ruth Calder, Shetland has found a new rhythm. Calder’s pragmatic, sometimes blunt style contrasts beautifully with Tosh’s quiet empathy, creating a partnership built on tension, trust, and grit.

The chemistry between Jensen and O'Donnell brings fresh energy — a battle of instincts that drives the story forward. While Tosh sees people as victims of circumstance, Calder sees predators — and this season will test which one of them is right.

🏴 A Decade of Mystery — Why Shetland Still Captivates Audiences

For over 10 seasons, Shetland has mastered what few shows can:turning bleak landscapes and quiet characters into a slow-burning symphony of human emotion and crime.

• 🌊 The Shetland Islands remain an atmospheric co-star — beautiful, haunting, and indifferent.

• 🕵️ Each case reveals how isolation can protect — or destroy — a community.

• 
  

• 💔 The writing never shies away from moral grayness — every truth comes at a price.

Shetland doesn’t just ask who did it. It asks why we keep secrets even from those we love.
