Philippe Malaiseau, writer and historian, being deceased before to have completed his study of
Charles The Great, the editor dispatches in Fontbonne the young writer Marc (
Jacques Weber). In Fontbonne five women are: Julie (
Claude Jade), very particular and charming secretary who allures Marc, the old mother of Malaiseau (
Mary Marquet), Marianne (
Anny Duperey), the distant widow, Christine (
Cécile Vassort), the cousin, and Melisa (
Nicoletta Machiavelli), an Italian friend. The four women all are related to Malaiseau. Did he really die by a simple accident? Marc continues a kind of investigation in the arms of Christine, of Julie and of Melissa which, in turn, succumb to its charm and him entrust force details which strengthen its conviction: Philippe was indeed assassinated... In agreement with Marianne, he will make "sing" Melissa, Julie, Christine and Mrs Malaiseau, accomplices in the murder of Philippe. And those to accept its requirements: Doesn't Marc make, henceforth, part of the family? ==External links==
