The six-episode story follows war veteran David Budd protecting Home Secretary Julia Montague amid attacks, surveillance debates, and institutional conflicts, with the central tension arising from personal duty versus political beliefs. No element of the premise centers identity politics, systemic oppression narratives, or critiques of traditional norms, keeping the focus squarely on national security and civil liberties. Creator Jed Mercurio has stated there is “definitely no political message” beyond broad consensus views on those topics, and he placed female characters in authority positions such as Home Secretary, explosives expert, and sniper strictly for plot reasons.

Casting relies on established white British leads and supporting roles that align with the contemporary UK setting, with no race- or gender-swapping of canon characters. Reception controversies centered on alleged Muslim stereotypes rather than any progressive messaging, further confirming the absence of activist intent.
