The film records a day in a supermarket in the Brussels region. The story of this day's little events, both comic and touching, provides the general framework of the film. The situations which are conveyed through an accumulation of quick, light touches, highlight some of the ways we behave in connection with food, the repetitive element in our gestures and movements in this everyday, enclosed world which is so familiar. The film is based on the observation of a supermarket and the people who shop or work there. More and more of their various personalities emerge in the course of the day. They all have their importance: we get to know them from the outside, like people in a group photo where each has his own place. All these individuals cross each other's paths, meet each other, bump into each other again and fill in the framework of the film with a many-sided tableau.

The play takes place in Brussels, where Suzanne Beulemans, daughter of a wealthy brewer, is promised in marriage to Séraphin Meulemeester, son of a rival brewer. Both the young man and his father appear to be particularly motivated by the young bride's dowry. But Séraphin has a rival in the form of Albert Delpierre, a young Parisian intern at the Beulemans brewery, who is secretly in love with the young woman. Albert receives a confession from Séraphin, who tells him that he is having an affair with a worker with whom he has had a child. He promises Séraphin not to reveal anything to Suzanne, but she is informed by Isabelle, the house servant.
