It’s 1958 and trouble is brewing in the Cambridgeshire village of Grantchester. Reverend Will Davenport (Tom Brittney, Greyhound) relishes his role as a firebrand vicar, willing to rock the boat and challenge conventions to help people. But the very role he loves puts him at odds with his own ideals when his kind-hearted curate, Leonard Finch (Al Weaver) is caught up in a scandal. Will’s best friend, Detective Inspector Geordie Keating (Robson Green), finds his principles shaken, housekeeper Mrs. Chapman (Tessa Peake-Jones) is distraught, and Geordie’s wife Cathy (Kacey Ainsworth) is defiant. With new crimes around every corner, and morality and legality at odds, it’s going to take all of Will’s skill and empathy to navigate these choppy waters and help the ones he loves.
