Jim and Sue married young and, 20 years later, find themselves on holiday in Spain – an anniversary present from their children – with very little to say to each other. Jim can't bear to be separated from his mobile phone and his business and, while Sue wants to relax with a chick-lit novel, Jim's idea of fun is immersing himself in a heavyweight historical biography. On discovering that their pool is shared with the adjacent villa, they do all they can to keep themselves to themselves, but the glamorous young couple next door soon bring a new perspective to Jim and Sue's relationship.
