A police investigation collides with the security services and the Royal Navy in an atmospheric mystery from the makers of "Line of Duty," in which a fishing trawler's inexplicable disappearance leads investigators below the waves into a shadowy world of intrigue. When a crew member is found dead aboard the Trident nuclear submarine HMS Vigil, the Scottish police begin an inquiry. The Vigil must remain on patrol in order to maintain the UK's nuclear deterrent, so Detective Amy Silva is forced to join the crew on board to conduct her investigation. Meanwhile, Detective Kirsten Longacre follows leads back on land. As the two pursue parallel trails, the case grows more sinister and broadens to include the highest levels of government and the British navy.

2/5
What we’re left with is a mystery designed to wrongfoot the viewer to a tedious degree, which plays out over a backdrop of urgent real-world jeopardy. Unfortunately, those two things end up cancelling each other out. Go to Full Review

Though Jones is a very good actress, Silva isn’t charismatic, strong or likeable enough to be the main character and carry the lead role. Go to Full Review

Vigil gets it just about right, asking pertinent questions about the climate emergency without lecturing, while still allowing itself the luxury of imagining that someone is coming to fix things. Go to Full Review
Barbara Ellen Observer (UK) Sep 8, 2026
The show puts in the effort to be an intellectual thriller, and there is elegant characterisation from Jones and Leslie. It just needs to streamline the plots so viewers can keep up. Go to Full Review
Charlotte Ivers Sunday Times (UK) Sep 8, 2026
I’ve watched so many of these police romps that it’s almost impossible to make me feel any tension. Go to Full Review

4/5
The unspoilt landscape of Svalbard, with its luminous skies and frozen mountains, has an almost lunar beauty, and gives the drama a special appeal. Go to Full Review

Dave C @RT09838700 1 day ago It was OK. Predictable and often eye-roll-inducing, it showed the glimmers of change and of more tension, and then let it return to more basic writing and performances See more Robert C @RT28451100 2 days ago Starts off well but becomes an exercise in one more plot twist after another to become silly to the point of unwatchable. If only the promise of location and actors in this series, were given a plot it deserves. in the first few episodes it seems so, but then unnecessary twists rather than developing any depth ruin what started off so promising. A Shame could of been great. See more Martin A @Hypercritt 4 days ago I enjoyed the first two seasons, but this latest Arctic adventure is cringeworthy. Putting aside the unlikelihood that a couple of very ordinary Scottish police detectives/lovers would be running a case involving the Russian FSB and a bio weapon that could wipe out all life on earth there is plenty to make you weep with disbelief in this one. Already in series 2 I was getting weary of the main characters' gay relationship. Because it was totally lame and unconvincing. Rose Leslie looks like a 14 year old tomboy on a school geography trip (who forgot to put her make up on.) The 12 ish daughter of Suranne Jones character, who is now calling Leslie "Mummy", is bravely bearing the pain of losing her dad (dead) and now being abandoned by Mummy 2 and Mummy 3 (aka Mummy 2's latest bedtime companion whom she "Really loves, even though I'm not very good at it sometimes". Yep. You really aren't, Jonesey.) The plot is so laughably confusing anyway it's like the writers are taking the Mick. See more John S @JohnSmithReviews Sep 19, 2026 Woke programmes are so horrendously dull. See more Adhit B @AdhitBennet Sep 19, 2026 Propaganda! How distasteful to slander other countries. Now make another series using the same plot to defame Israevil See more Tam R @RT63319486 Sep 19, 2026 Absolute pish ... the two women swooning over each other is frankly shite. Scenery is good .. plot is overly boring. See more Read all reviews
