Richard is a successful advertising photographer who is satisfied with himself, his career and his wife. He thinks he's the perfect spouse, but only until the day that his wife Charlotte discovers a new Ideal Man in an online dating site. A check of their data turns up an incredible 98% compatibility with a certain Thomas, a teacher. Her own husband, in turn, scores a mere 14%. Charlotte starts having doubts about her allegedly solid marriage, becomes curious and meets the teacher. Richard may be tolerant, but he wasn't expecting his rival to score in real life! He starts phantasizing about his exemplary marriage being endangered just before their 25th wedding anniversary, and how his retirement plans on a Greek island may come to naught. He sets out for Greece alone at first, then starts seeing things anew – and fighting for Charlotte.
