Deadpoint is currently in production, Channel 4 has confirmed, and the five-part action thriller will take audiences deep into the Welsh mountains…

This new “nerve-shredding” series comes from the producers of Netflix’s smash hit, Baby Reindeer. So we know we’re in good hands.

Viewers will follow a  group of Welsh climbers who encounter a far-right faction plotting a violent act in their local mountains. Well it’s certainly topical.

Here’s everything we know so far about Deadpoint on Channel 4, including plot, cast, start date, and location.

What’s the plot of Deadpoint on Channel 4?

So, what’s Deadpoint all about? The drama follows a group of climbers torn apart by a fatal accident. As if that wasn’t stressful enough, they then find themselves facing a far-right organisation known as the Justice Crusade.

As the story unfolds, the climbers must confront the unforgiving landscape of Eryri National Park. There’s also the dangerous individuals who have chosen it as the setting for their violent mission. They are led by the charismatic but unstable former soldier Fairweather (Micheal Socha in a role made for him).

A synopsis tell us: “Set amongst the awe-inspiring and unforgiving landscape of Eryri National Park, a close-knit community of climbers is left reeling after a tragic accident on a mountaineering expedition.  As the group is torn apart by grief, Aaron blames himself for the accident and abandons his hometown, to the fury of his sister Seren.”

The “unique wilderness thriller” explores themes of loss, radicalisation and survival. Channel 4 adds: ” Deadpoint is a literal cliffhanger, grounded in the tensions existing in our society today, exploring who we are, who we pretend to be, and what we do when the rope snaps.”

Who wrote the series? Who’s the director?

Matt Hartley wrote and created Deadpoint. It’s his first major step into television drama. Channel 4 has called his script bold, tense and character-driven.

The series is produced by Clerkenwell Films, the multi-award-winning company responsible for acclaimed dramas Baby Reindeer, The End of the F***ing World and Misfits.

Meanwhile, German filmmaker Marco Kreuzpaintner acts as the lead director. He is responsible for shaping the first episodes of the series. He’s worked on high-profile titles including The Lazarus Project, Bodies and the upcoming historical drama Those About to Die.

Further episodes will be directed by Laura Scrivano, who has credits on Wedding Season, The Lazarus Project and Alice. 

Where is Deadpoint on Channel 4 set?

The C4 series is set and filmed in Wales, with Eryri National Park providing a striking but hostile backdrop. The mountains are more than just scenery, becoming an essential part of the drama. They will reflect both the physical and emotional challenges faced by the characters.

Eryri National Park was formerly known as Snowdonia. It was renamed Eryri “to prioritise and promote the Welsh language and its cultural heritage”, following a decision by the Eryri National Park Authority in 2022 to use Welsh place names in all official communications.

It’s Wales’ largest National Park, covering a total of 823 square miles. It’s home to over 26,000 people.

The show is produced by Clerkenwell Films, part of BBC Studios, with support from the Welsh Government via Creative Wales. The backing reflects a growing trend of major productions being filmed in Wales. These productions take advantage of both the landscapes and local talent.

Gwawr Lloyd, Interim Head of Drama at Channel 4, said: “Deadpoint is a bold and incredibly tense thriller that places characters and their journeys at the heart of high-stakes action. Matt Hartley’s debut script is as gripping as it gets and all set against the breathtaking backdrop of the Eryri mountain range.”
