Returning: Grantchester

Season 6 of Grantchester will screen on ABC from early October.

Robson Green & Tom Brittney return for more period mystery cases. This series debuted in the UK earlier this month and has already been renewed for a seventh season.

It’s 1958 and trouble is brewing in the Cambridgeshire village of Grantchester. Reverend Will Davenport (Tom Brittney) relishes his role as a firebrand vicar, willing to rock the boat and challenge conventions to help people. But the very role he loves put 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.

Will and Geordie’s friendship is also tested when an old army buddy comes back into Geordie’s life. Johnny (Shaun Dooley) is a lawyer, representing the very people Geordie puts away. But the bond forged between them in a prison camp in Burma means Geordie is drawn to this morally grey character, particularly when Will’s idealism starts looking like naivety, from a certain point of view.

Despite their differences of opinion, Geordie and Will tackle a variety of cases together, from a murder during a summer break at a holiday camp, to contested adoptions, the deadly cut and thrust of a parish election, American soldiers racing cars, audacious robberies, student CND protests, and even a murdered music producer.

It seems morality and legality are at loggerheads at every turn. But when the question of what true justice really means comes uncomfortably close to home, it’s going to take all of Will’s skill and empathy to navigate these choppy waters and help the ones he loves.

Saturday, 2 October at 7.30pm on ABC.
