Secret Service

ITVX • Apr 27 • 2026

DramaEspionage

A British intelligence officer races against time to uncover a UK politician's potential ties with the Kremlin, risking her reputation and family, as a murder and election loom.

Strongest Match

Secret Service keeps the same kind of spy crisis where loyalty and marriage get squeezed at once, with deadline pressure that never lets the protagonist breathe. Election stakes and a murder investigation run in parallel, so every workplace decision in Secret Service feels like it could cost him his job and his relationship, just like Betrayal.

Slow Horses

Apple TV • Sep 24 • 2022

CrimeDrama

A dysfunctional team of MI5 agents navigate the espionage world's smoke and mirrors to defend the UK from sinister forces.

View show

Why This Pick

Slow Horses delivers the same British workplace suspicion, where tradecraft is messy and trust is rationed, and the danger grows out of office politics. The team’s humiliating failures and grudges create constant pressure on competence, giving Betrayal’s paranoia a drier, funnier edge while keeping the stakes personal.

The Capture

BBC One • Jun 18 • 2019

CrimeDrama

After ex-soldier Shaun Emery's (Turner) conviction for a murder in Afghanistan is overturned due to flawed video evidence, he returns home a free man to his young daughter. But when CCTV footage from a night out in London comes to light, Shaun's life takes a shocking turn and he must soon fight for his freedom once again. With DI Rachel Carey (Grainger) drafted in to investigate Shaun's case, she quickly learns that the truth can sometimes be a matter of perspective. Should she trust Shaun Emery?

View show

Why This Pick

The Capture shares Betrayal’s obsession with who can be believed when institutions control the story, turning surveillance into a weapon against the wrong person. Unreliable evidence and shifting moral ground keep the tension cerebral and tense, but it’s colder and more mystery-driven than Betrayal’s marriage-and-career collapse.
