The Undeclared War
The battle line is online
Created by Peter Kosminsky
On Channel 4
A tense, cerebral espionage thriller about defending democratic systems from cyber-attack, grounded in contemporary politics but undercut by self-aware absurdism and institutional embarrassment.
In the post-pandemic world of 2024 during an upcoming British general election involving the UK’s first Black Conservative prime minister, a leading team of analysts at the heart of the UK’s NSA-style spy agency GCHQ attempt to ward off a cyber-attack on the country’s electoral system.
