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.

Death Valley follows the unlikely crime-solving partnership between eccentric national treasure John Chapel, a retired actor and star of hit fictional detective TV show ‘Caesar', and disarming Welsh detective sergeant Janie Mallowan.

Thrown together by the murder of John's neighbour, John and Janie are an odd, yet hilarious duo with opposing instincts. Every week, they get to the bottom of gripping murders, with various stunning Welsh locations providing a backdrop to their investigations.
