Delphine, a saleswoman in a French fry stand, and Roland, a campsite warden, fall in love at first sight. They are in perfect love, but their big dream is to buy a house. Thanks to a friend, who puts together a fake file to obtain a loan, they acquire a piece of land and order a house in kit. From then on, Delphine and Roland will have to foil the traps that will accumulate before
The construction of their kit house has become their obsession and a metaphor for the difficulties of their own couple.
