Charles Duchemin, a well-known gourmet and publisher of a famous restaurant guide, is waging a war against fast food entrepreneur Tri- catel to save the French art of cooking. After having agreed to appear on a talk show to show his skills in naming food and wine by taste, he is confronted with two disasters: his son wants to become a clown rather than a restaurant tester and he, the famous Charles Duchemin, has lost his taste!

The story centers around a graduating class of "less-gifted" students in a private Versailles high school. Only a miracle has brought the students this far along, and after a practical joke misfires and the whole school is dynamited, the students are in deep trouble. They have to present themselves in court for their punishment and it could not be worse: If they don't pass their high-school graduation exams, they go to prison!
