What to Expect

PremiereLens read

Secret Service runs on compressed time: a murder, a looming election, and a suspected Kremlin connection all pressing in at once on a British intelligence officer who cannot afford to be wrong. The plotting is procedural but not slow, built around a single protagonist carrying the full weight of the investigation while her professional standing quietly erodes around her.

Her marriage is not backdrop; it is another front in the same war. The question of who can be trusted cuts through her domestic life as sharply as it does through the political corridors she is trying to map, so the deception never stays abstract. Loyalty gets tested from multiple directions simultaneously, and the show does not let either pressure release the other.

Betrayal

ITVX • Feb 8, 2026

ThrillerEspionage

When an assassination links a veteran MI5 agent to a conspiracy, he races to find the truth and protect his career, his marriage, and his country.

View show

Strongest Match

Betrayal keeps the same pressure-cooker mix of espionage duty and marriage strain as Secret Service, with loyalty tested until every conversation feels dangerous. A veteran operative gets boxed in by suspicion at work and at home, so the tension tightens through distrust and secrets, then turns darker and more personal.

The Undeclared War

Channel 4 • Jul 21, 2026

DramaThriller

Set in 2024, in the run up to a British general election, THE UNDECLARED WAR tracks a leading team of analysts buried in the heart of GCHQ (the UK's version of the NSA), secretly working to ward off a cyber-attack on the country's electoral system.

View show

Why this pick

The Undeclared War delivers the same election-stakes tension and secrecy-heavy atmosphere as Secret Service, but it leans harder on analysts under strain. You get tense meetings, coded communications, and workplace pressure that builds dread step by step, slower and more bureaucratic than the faster, more intimate domestic threat in Secret Service.

Red Eye

ITVX • Jan 1, 2026

ActionCrime

Follows London Detective Hana Li, whose investigations lead her into the world of National Security.

View show

Why this pick

Red Eye brings Secret Service’s London urgency into a faster, more kinetic mystery that keeps escalating in front of you. A detective case spirals into national security stakes with constant momentum, tight suspense in contained spaces, and danger that feels immediate, making it quicker and stranger than Secret Service’s marriage-and-betrayal countdown.
