In season 10, as DI Geordie Keating and Reverend Alphy Kottaram continue to work together as a crime-solving duo in scenic Grantchester, they must also support each other through changing times, family struggles, and personal secrets. This season, Alphy feels like he's found a home, but he's forced to confront secrets he's kept close to his chest. Will he be able to let anyone fully in, or must he confront truths about himself first?

Season 9 begins in 1961, a period of accelerated social change throughout the UK. Will has begun to think of new possibilities outside the tiny village of Grantchester, and Geordie and Cathy are struggling to cope with the realities of Esme being out in the world. New drama enters the picture when Reverend Alphy arrives to a less-than-warm welcome.

Will is the happiest he's ever been but his world will be rocked by a terrible accident. He's always preached the word of a compassionate God – but how can he now, when his despair leads him on a dangerous downward spiral?

Geordie has found a new contentment in his relationship with Cathy, but when they are both confronted with shocking announcements at work their happiness is threatened. As Mrs C, Leonard, Jack and Daniel rally around, both Will and Geordie find themselves in unfamiliar, emotional waters and murder is always around the corner. 

The eighth season of Grantchester will range from Speedway to spies, exploring the lives of invisible women and the very visible problems caused by Leonard's new vocation which may, once again, find him battling the law.    

Exploring faith, forgiveness, and redemption – this explosive series tests Will and Geordie to the limit.
