Each week, Tom and Louise meet for a quick drink in the pub before they go to meet their marriage counsellor. Married for years and with two children, a recent incident has exposed the fault lines in their relationship in a way that Tom, for one, does not wish to think about. In the ten minutes in the pub they talk about the agenda for the session, what they talked about last week, what they will definitely not talk about with the counsellor, and how much better off they are than the couple whose counselling slot immediately precedes their own. Over the ten weeks that follow Tom and Louise begin to wonder: what if marriage is like a computer? When you take it apart to see how it works you might just be left with a million pieces you can't put back together . . .
