A member of Will's own congregation is found cuddled just before a church fundraising event. It becomes clear that the victim, Neil Hughes, was not quite the upstanding member of the community Will believed him to have been. And secrets emerge that make Will question how well he really knows any of his parishioners.
Set against the backdrop of the real hamlet of Grantchester, the drama focuses upon the life of Sidney Chambers, a charismatic, charming clergyman who turns investigative vicar when one of his parishioners dies in suspicious circumstances.
