An ordinary accident on a country road, a car driving at excessive speed, rolls over several times... The victim is a forty-year-old architect, Pierre, well-to-do, separated from his wife Catherine, with a grown son and a mistress Helene. He is at the age where one asks oneself questions. Ejected from the car, lying in the grass of the meadow, half conscious but already dying without knowing it. Pierre relives a few episodes from his past, rediscovering the sweetness of the "things of life", until the moment when, dreaming with his family, next to the family boat, he sinks without recourse into death.
