Shetland Season 11 Promises A Gripping New Mystery Filled With Twists And Emotional Drama

The next chapter of Shetland is officially taking shape, with filming now underway and Ashley Jensen and Alison O’Donnell returning as DI Ruth Calder and DI Alison “Tosh” McIntosh.

The BBC crime drama, based on the acclaimed novels by Ann Cleeves, has become a fixture of the broadcaster’s drama lineup since its debut in 2013. Season 11 will once again take Calder and Tosh into a complex investigation, this time involving a historic murder with consequences that reach into the present day.

The new season is being described as a gripping story packed with twists, turns and emotional weight, while the dramatic landscape of the Shetland Isles remains central to the series.

A mysterious discovery sets the investigation in motion

Season 11 begins when a car is recovered from the water, revealing a disturbing discovery inside its boot: the decomposed, skeletal remains of an unidentified man.

With no immediate answer to the man’s identity, the investigation turns toward the history of the vehicle and its former owner — a respected local GP who left the Shetland Isles nine years earlier amid troubling rumours.

Calder and Tosh begin digging into the doctor’s state of mind and the lives of the people he left behind. What initially appears to be a search for the identity of an unknown victim soon leads the detectives into increasingly dark and dangerous territory.

According to the season synopsis, the historic murder will “forever change the lives of all those connected in the present day.”

The case promises to test the team as they attempt to uncover what happened and why the truth has remained hidden for so long.

Ashley Jensen will once again lead the series as DI Ruth Calder, with Alison O’Donnell reprising her role as DI Alison “Tosh” McIntosh.

Jensen took over as the show’s central detective following Douglas Henshall’s departure as DI Jimmy Perez at the end of season seven. Her arrival introduced a new dynamic to the long-running drama, while O’Donnell’s Tosh has remained an important part of the series.

The show was among the BBC’s five most-watched drama series of 2025, highlighting its continued popularity several years after its original launch.

A darker case against the beauty of Shetland

For Gaynor Holmes, Commissioning Editor for the BBC, the appeal of season 11 lies not only in its mystery but also in its emotional impact.

She described the new series as being “brimming with twists, turns, and the kind of emotional punch that keeps viewers hooked.”

Lead writer Paul Logue is also credited with delivering a “gripping, atmospheric story,” with the wild beauty of the Shetland Isles remaining at the heart of the drama.

Holmes praised the returning leads, saying that Alison O’Donnell and Ashley Jensen head a strong central cast alongside an impressive group of guest performers and crew.

The combination of the rugged Scottish setting and another intricate crime story remains one of the defining elements of Shetland.
