If you’re looking for a gripping new British crime drama, ITV has delivered a winner with Protection — a tense, twist-filled thriller that’s keeping audiences hooked.
Starring the brilliant Siobhan Finneran (Happy Valley, The Witch) in her first lead role, the six-part series follows Detective Inspector Liz Nyles, a dedicated witness protection officer whose life spirals into chaos when a major security breach puts everything — and everyone — at risk. Compromised by a secret affair with a colleague, Liz must fight to uncover corruption within her own unit while protecting the witnesses under her care.
With strong supporting performances from Katherine Kelly and Nadine Marshall, Protection blends high-stakes drama, family tension, and shocking twists that will keep you guessing until the final episode.
The series first dropped on ITVX and ITV1 in March 2025 and has since gained a strong reputation for its intelligent writing and intense atmosphere. Critics and viewers alike are praising Siobhan Finneran’s commanding lead performance.
