Antoine (Jean Rochefort) has always had a thing for beautiful hairstylists. As a young boy, he lusted after the beautician who cut his hair, and vowed that one day he'd marry a hairdresser. His quest comes to an end when, as an adult, he meets gorgeous Mathilde (Anna Galiena). Their marriage doesn't dampen his erotic desire for her. If anything, he becomes even more sexually obsessed with her. In fact, the two rarely leave the hair salon, until the fateful night that Mathilde ventures outside.
