Set in 2024, The Undeclared War tracks a team of leading analysts secretly working to ward off a series of cyber-attacks on the UK ahead of a general election. Buried in the heart of GCHQ, a routine stress test of internet infrastructure goes awry, propelling 21-year-old intern Saara Parvin (Hannah Khalique-Brown) to operate on the invisible frontier of high-stakes cyber warfare.  

Created by Peter Kosminsky (Wolf Hall), the series is the result of years of meticulous research with the aim of lifting the veil on the most urgent battle of our time.

The series also stars Simon Pegg, Maisie Richardson-Sellers, Adrian Lester, Alex Jennings, Mark Rylance and Kerry Godliman.

Peter Kosminsky commented: “The Undeclared War has been many years in the making. It imagines how the next few years might play out in the domain of cyber warfare – a battle unseen by the public but with potentially devastating consequences. In my work, I’ve tried to shine a light on aspects of public policy which affect us all but where the details of what is taking place, often behind the scenes, are not well understood. I hope this drama will give audiences an insight into a world certain to impact our lives significantly in the years ahead.”

The Undeclared War will launch on Channel 4 and All 4 on Thursday 30th June at 9pm.
