Alain and Irene, both in their forties and married for 15 years, have reached the midpoint of their lives. It is the year 2004. They have left love behind - now begins the vegetarian phase of their lives. When a close mutual friend passes away, old wounds are reopened for both of them - along with the memory of a summer on the French Atlantic coast, when their youth came to an end. Now, more than 20 years later, Alain encounters his great love Babette again. And Irene suddenly falls for a blonde Dane who sits down next to her at the opera.
