ITV has released a first look at its upcoming drama-thriller series, Protection, which was filmed across the Liverpool City Region. Filming for the new series started in September 2023, at locations including Wirral, Liverpool, Knowsley, Sefton and Halton.

The six-part thriller follows Detective Inspector Liz Nyles (Siobhan Finneran) at the heart of a security breach within her witness protection unit.

Professionally compromised by a secret affair with a colleague, she is determined to uncover the true source of corruption within the police. Liz will stop at nothing to redeem herself, the reputation of her lover, and to keep her witnesses and her own family safe. Even if it means breaking all the rules.
