An advertising photographer, François, has agreed to sell the poetic script of one of his friends to a porn-maker without his knowledge. But Christine, François' fiance, doesn't want him to do so, especially when the naive friend has succeeded in recruiting the young daughter of his employer to play in what he thinks is a romantic love movie.
The whole intrigue is centered around carte-blanche documents kept in a vault. Whoever fills in the blank becomes the owner of a revue. Big money is involved. The nephew of the owner of the vault is trying to cheat his uncle and have his name in the documents. Everything is even more complicated because the manager of the bank has a finger in the pie, too. Who but a humble bank-teller (Pierre Richard) will ruin the scheme?
Govert Miereveld is a lawyer from a small Flemish town who also teaches in a school for girls. He harbors a secret love for one of his young students, Fran, whom he loses touch with after her graduation. Some time later, Miereveld has to attend an autopsy, and the shock of the experience deeply affects his mental balance. He finds out - or he believes so - that Fran has become a popular singer. He arranges to meet her to finally reveal his feelings. An ambiguous but perhaps tragic denouement follows which might be a figment of the protagonist's disturbed mind.
