Will, reeling from his family tragedy and daunted by the choice he now faces, seeks distraction in Geordie's world. A curious new case unfolds: the murder of a Teddy Boy at a dance hall, which Geordie concludes is proof that the country's truly gone to the dogs. It's a view fuelled by the impotence he now feels regarding Cathy's troubles at work and his daughter Esme's teenage rebellion.
Away from her life at the vicarage, Mrs C is feeling lost, while Cathy is left shaken by another encounter at work. Leonard is adrift, hiding at Daniel's house and reeling from his encounter with Will. Can Grantchester's new vicar, already dealing with demons of his own, calm Geordie's anger long enough to uncover who was really behind the boy's death?
