Saturday evening. We have a date with friends and Pierrot has finally obtained his mother's slightly worried authorization. He runs down the indefinite staircase of the immaculate H.L.M., planted firmly in the mud of the suburbs, to meet up with the others. The others are older than him on the whole, but what they have in common is the desire for something to change, this weekend, and for things to get moving. This is especially true for those with scooters who, in close ranks, can scare pedestrians, hug cars and taunt the marshals. Pierrot will be taken in rump like the girls, Thérèse behind Jacquy, Monette behind Christian.

A film made up of four sketches. In Marc Allégret's Sophie, a naive high-school girl invents a love affair with her mother's lover. But it's a guitarist with whom she falls in love. In Françoise, by Claude Barma, a young woman returning to France after living in the United States has an affair with her best friend's lover. In Antonia, by Michel Boisrond, a middle-aged woman tries to convince her ex-lover that she still has many assets to seduce. In Ella, by Jacques Poitrenaud, a Pigalle dancer meets a man in a cab.

In this mystery, a nouveau-riche Frenchman returns to his Parisian home after finding a fortune in Africa. He is looking for a wife and begins advertising in the newspaper. Instead he finds himself victimized by con-artists.
