Broadcast for the end-of-year holidays, this second diversion (which follows Derrick contre Superman) is a crazy cartoon show mixing original sequences presented by Valérie Payet and Philippe Dana with redoubled excerpts from cartoons with Bugs Bunny, Daffy Duck... and films with Steve McQueen, Burt Lancaster, Jack Nicholson, Jean Gabin, etc. This is the second of the three TV films of the Grand Détournement.

Bois d'Enghien, engaged to a young girl from a good family, has to break up with Lucette Gautier, his mistress, a dilettante of salons. Not having been able to tell her of his break-up, he finds her at her fiancée's house, invited for the event. A Mexican general, jealous of his rivals, arrives and complicates the situation, as does a notary clerk, Bouzin, a singer in his spare time.
