It's 1956 -- a year since Amanda left Grantchester, and the post-war rulebook is being torn up. Sidney Chambers (James Norton) is feeling adrift, a man without a cause -- until American civil rights activist Violet Todd arrives and fires up his need for social justice. But with a cause this dangerous, Sidney might not be around forever. Soon there's a new Vicar of Grantchester, firebrand Will Davenport (Tom Brittney). Idealistic and energetic, Will embraces the change sweeping the nation and wants to make the parish his own. He finds himself drawn into Inspector Geordie Keating's world of murderous plots and crimes of passion that unearth his own troubled past. And while Will embraces the future, Geordie (Robson Green) is left entirely baffled by it. Navigating a world without Sidney, where does he fit in?
