Two cousins related by marriage, Marthe and Ludovic, meet at a family wedding for the first time. Marthe is the bride's daughter and Ludovic is the groom's nephew. After a raucous wedding reception with plenty of dancing and drinking, Marthe and Ludovic are left waiting for their respective spouses, Pascal and Karine, who are off having sex. While they wait, they get to know each other: Marthe is a secretary and Ludovic is a dance instructor who changes his occupation every three years. Later, they dance together. Eventually, Pascal and Karine show up, slightly disheveled, and the couples part.
