Every year Lady Repton opens up her grand estate to host 'Cherringfest' - the Cotswold's favourite music festival. And this year will be special, featuring not just the return of the legendary and infamous metal rock band, Lizard...but also the home debut of the young and wildly successful new group, Unlost. But what should be a summer weekend of fantastic music, food and fun for all, turns frightening when murder is threatened, and one performer is nearly killed. Soon Jack and Sarah are in a race against time, trying to untangle a web of jealousy, egos and revenge before this Cherringfest ends in a deadly climax... Set in the sleepy English village of Cherringham, the detective series brings together an unlikely sleuthing duo: English web designer Sarah and American ex-cop Jack.
