1983 film by Michel Caputo

Mr. Pelletan's rascal son Bébert son got another F for playing in class. His punishment is an essay on the Merovingian king Dagobert. All they know is he had eight wives and reunited Francia. The ignorant knave's irreverent imagination turns that into a harem and a ludicrous war without armies, loaded with anachronisms, in a race against rival king Charibert for the crown of Reims. The king's right hand, archbishop Eloi, the later patrons saint of carpentry, is portrayed as an inventor.

At a gathering of would-be society debauchees, the Baron Plessis de Regard and the attractive young Nathalie hatch their individual plans to use sex to respectively ruin and punish their selected enemies. The Baron's plan is to scupper the political ambitions of right-wing parliamentary candidate Colonel Montvilliers by setting him up with a female companion and publicly exposing his new-found vices. Nathalie's quest is of a more personal nature, to destroy her estranged father Charles Leroy-Merville by corrupting his innocent 17-year-old daughter Sophie, a task she intends to achieve by securing employ as the girl's summer tutor.
