Protection on ITV is set to be one of the most talked-about British crime dramas of 2024. With six episodes, this show, created and written by Kris Mrksa (The Slap, Requiem) delves into the murky and morally gray world of witness protection. The show, which is led by Siobhan Finneran, promises an interesting story and a complex look at a system that is often made fun of in pop culture. The show was filmed in the northwest of England, which has both beautiful and dangerous places that add to the show’s realistic plot.
“The Story of Protection”
Detective Inspector Liz Nyles (Siobhan Finneran), a seasoned witness protection officer who gets caught up in a web of betrayal and plots, is at the center of Protection. At the start of the story, there is a shocking breach at a safe house—complete with a shooting and the mysterious presence of a coworker Liz was seeing romantically. Because of this tragedy, a chain of events happens that forces Liz to deal with corruption in her unit which puts her witnesses’ safety and the team’s reputation at risk.
Liz is trying to find the truth, but she has to deal with a morally murky world where criminals are often the ones being protected. Liz’s mission to reveal the plot tests her limits, loyalty, and values as she juggles her personal life with her job as a police officer.
Where Was ITV’s Thriller Protection Filmed?
The filming for Protection took place in real places from July to September 2023, which fit with the show’s dark tone. Here is a list of the main places where movies are shot:
Liverpool, England
Many of the productions took place in and around Liverpool. The mix of old buildings and new developments in the city’s urban landscape made for the perfect setting for the show’s intense drama. The Liverpool Film Office was very important to the production and made sure that the show’s dark tone matched its visuals.
The cast, which included Siobhan Finneran and Katherine Kelly— was often seen in important places like the Georgian Quarter and the busy docks in Liverpool. When talking about Liverpool, Finneran said:
“Liverpool has an incredible energy. It’s the ideal city for a story like Protection — full of character and contrasts.”
Wirral towns: Birkenhead
A nearby town called Birkenhead was very important to Protection. Its industrial, quieter streets were very different from Liverpool’s busy ones, which drew attention to the show’s themes of privacy and being alone. Several scenes were shot in nearby housing projects and abandoned buildings, which added to the gritty realism of the situation.
Runcorn, Cheshire

One of the most interesting places was Runcorn Shopping City, a huge shopping center where many important scenes took place. Dramatic events happened in parking lots and even an arcade while this location was being filmed. Representative for Weaver Vale, Mike Amesbury, was able to watch the filming.
Kris Mrksa, the author, talked about what inspired him to write the series.
“The murky world of witness protection, where even criminals are sheltered to serve a greater purpose—was the perfect context for exploring thorny moral questions. Working with such a —talented cast and crew has been an absolute privilege.”
