ITV shares first-look at Game of Thrones star's 'intoxicating' new thriller

ITV has unveiled the first glimpse of its upcoming thriller, Coldwater. The six-part series, set to premiere this autumn, stars Andrew Lincoln of The Walking Dead fame andIndira Varma from Obsession.

Set in the fictional Scottish village of Coldwater and filmed in and around Glasgow, the plot revolves around Andrew's character John, who finds himself at the heart of eerie occurrences as past traumas resurface.

John relocates his family to the rural tranquillity of Coldwater in an attempt to distance themselves from London. However, he soon grows frustrated with his mundane existence as a middle-aged stay-at-home dad, his suppressed anger threatening to disrupt his life as he knows it.

Following an identity crisis in London, where John failed to intervene in a violent playground confrontation, he yearns for a more peaceful future for his family, only to encounter further disturbances in Coldwater.

Upon arrival, he quickly forms a friendship with his next-door neighbour Tommy, portrayed by Ewen Bremner. Tommy is a charismatic, self-assured man and a dedicated husband to the local vicar Rebecca, played by Eve Myles, reports the Express.

On the surface, Tommy appears to be a man of faith, a community stalwart, and the self-proclaimed leader of the village's all-male book group.

Initially impressed and somewhat intrigued by Tommy, John soon finds himself ensnared in his web.

Meanwhile, his spouse Fiona, portrayed by Indira, harbours deep resentment towards him following their relocation to Coldwater, as what was meant to be a fresh start has utterly failed to rekindle their deteriorating relationship.

As her husband grows increasingly close to their mysterious new neighbour, Fiona's alarm bells begin ringing and she starts questioning whether Tommy is genuinely who he claims to be.

John's long-suppressed fury eventually erupts with catastrophic consequences, leaving him surprisingly beholden to his newfound companion, completely oblivious to the fact that Tommy is concealing deeply disturbing secrets of his own.

It's only when a string of disturbing events begins unfolding that John starts questioning Tommy's true identity.

The synopsis hints: "This is the story of a normal man, in a normal marriage, who finds himself in a far from normal situation.

"A man who discovers a newfound sense of his own power, right at the moment he falls under the influence of someone incredibly dangerous."

Coldwater has been penned, conceived and executive produced by David Ireland, with Lee Haven Jones (Doctor Who) helming the opening three episodes and Andrew Cumming (Shetland) taking charge of the latter half.

Speaking previously, creator David revealed in a statement: "Cold Water started with a question I was asking myself. Where do I want to live - the countryside or the city? Such an innocent beginning, but from it came this dark, funny, twisted thriller.

"I was delighted when Sister loved the script and thrilled when ITV decided to commission it.

"And I'm amazed we've managed to attract such a peerless cast, led by the formidable Andrew Lincoln. I hope viewers will find it intoxicating."

Coldwater is set to premiere on ITV1, ITVX, STV, and STV player this autumn.
