Plot Synopsis

Set in 2024, THE UNDECLARED WAR is a six-episode series that tracks a leading team of analysts buried in the heart of GCHQ, secretly working to ward off a series of cyber-attacks on the UK in the run up to a general election. When a routine stress test of internet infrastructure goes awry, 21-year-old GCHQ intern Saara Parvan suddenly finds herself operating on the invisible frontier of high-stakes cyber warfare. The series is a result of meticulous research by BAFTA award-winning creator Peter Kosminsky, lifting the veil on the most urgent battle of our time. In a thrilling cat and mouse game, Saara and the team at GCHQ must try to stay one step ahead and anticipate their opponents' every hidden move. The clock is ticking as a battle with high stakes and unpredictable enemies takes place entirely online, with very real consequences. But how do you win a war most of the public don't know you're fighting? THE UNDECLARED WAR made its U.S. debut on Thursday, August 18, 2022, as Peacock released all six episodes.
