1990s England. Ali and Caroline are neighbours but not friends in leafy Upley Rising. Ali battles with money troubles and multiple children while Caroline has rock star connections and always gets what she wants. Then there's respectable Robert, the third neighbour, whose life takes an unexpected turn.

Every December Ali, Caroline and Robert write up their year's news into cheery round robin newsletters for everyone they know. What a wonderful year it's been: Charles has been promoted twice, Max is the school orchestra's top tuba player and Clementine's child modelling career progression is meteoric. But what about the longstanding local murder mystery? Or the strange goings on at Upley Rising's 300 year-old summer festival?

Whose letters can you really believe?
