James Norton reprises his role as Sidney Chambers, the charismatic, charming, crime-fighting clergyman, and Robson Green returns as his partner in crime, Detective Inspector Geordie Keating, in the second series of Grantchester. It's 1954 and having lain his wartime past to rest, Sidney Chambers is in a good place. Booze and self-doubt have taken a back seat to his duties and congregation. He's growing up, and trying to lead a good life. But things are never easy and when Sidney finds himself wrongly accused of a crime, his unmasking of the real culprit will send shockwaves through the entire village. Sidney and Geordie's unlikely friendship has blossomed - they will do anything for one another - but as the story unfolds they will find that loyalty tested to the limit. A vicar keeps people's confidences. A copper is hell bent on exposing them. Will allegiance to the institutions they work for ultimately be Sidney and Geordie's undoing?
