About The Undeclared War

The Undeclared War is a dystopian crime thriller series set in a post-pandemic, post-Boris 2024.


In 2024, a leading team of analysts buried in the heart of GCHQ secretly works to ward off a foreign cyber-attack on the country's electoral system.

Critic Reviews

  • [An invisible cyberwar with Russia is] a terrifying prospect, and one that he [creator Peter Kosminsky] has brought pretty effectively to the screen without succumbing to the temptation to make the main characters swashbuckling or glamorous.

    Rating: 80/100
    The Times
  • This series exceeds expectations, guiding viewers by the hand through the complex world of cybersecurity - and then refusing to relinquish its grip until the final episode.

    Rating: 80/100
    Radio Times
  • Broad in scope and rarely letting go of its in-built tension, The Undeclared War feels like a fresh take on political drama.

    Rating: 80/100
  • It’s interesting stuff. But first you need to swallow the ludicrous idea that the only person capable of staving off World War Three has been in the job for two hours.

    Rating: 60/100
    The Telegraph
  • The central mysteries of The Undeclared War – who’s behind the cyberattack, and what are their intentions – may be enough to carry you through. The series is at its best when it’s ratcheting up the tension. Just don’t expect it to convince when it comes to anything deeper.

    Rating: 40/100
    The Independent
  • It moves at a glacial pace and the GCHQ staff have the air of reluctant office workers on data entry shifts, boredly tapping at their keyboards until it’s time for a statutory tea break – rather than people frantically trying to hold off an enemy assault that could kill thousands and hurl the nation back to the middle ages, or at least the 1990s.
