ITV's 'Protection' Debuts as a Tense Crime Drama with Complex Characters

The new series follows DI Liz Nyles as she navigates a botched witness protection case while facing personal and professional challenges.

The show centers on DI Liz Nyles, played by Siobhan Finneran, as she works to protect a family in witness protection while investigating a leak in the operation.
The McLennan family, key witnesses in a trial against drug kingpin Eddie Crowther, face danger as their safe house is compromised following a security breach.
Nyles' personal life, including an affair with a married colleague, complicates her efforts to uncover corruption and navigate suspicions from her own team.
The series features a strong ensemble cast, including Katherine Kelly as a determined investigator and Nadine Marshall as an officer probing internal corruption.
Critics praise the suspenseful storytelling and standout performances, particularly from Finneran, though some note familiar tropes in the crime drama genre.
