Set and filmed in Wales, the series broke records on its launch with the biggest overnight audience for a new scripted show in five years; the series averaged a strong 4.6 million average across 28 days. For Welsh audiences, Death Valley was the number one comedy across all channels and platforms in 2025.

Series two picks up a few months after the events of series one, Janie has been promoted to Detective Inspector and is busier than ever, with paperwork stacking up quicker than she can clear it. To make matters worse, she’s been ignoring John since finding out he’s been dating her mum. Janie’s hand is forced after a murder in a Community Payback group when DCI Barry Clarke forces her to bring John Chapel in as the department's consultant.

Series two sees John reluctantly re-enter the world of acting, on the set of an epic Welsh fantasy TV series, when the pair are called to investigate a murder. Will this foray into his old thespian passion ignite something once forgotten in John? One thing is certain, whether investigating a murder in a coastal fishing village, a sustainable commune or the competitive world of rugby, John and Janie will continue to bring justice to mid-Wales.
