The story of three candid and mischievous characters who live in the heart of the Bourbonnais: "Le Glaudius", a farmer who still ploughs with his horse and who doesn't give a damn about agricultural productivity and new technologies. "La Germaine", his wife who loves charm acts and the letter carrier, a funny civil servant, always ready to organize "trips".
A clique of four young teachers at a high school looks critically at their colleagues. To avoid falling in the same routine, they bring new ideas into the school lessons and play little games and pranks in their spare time -- sometimes get even more childish than their pupils. When they get opposition from the other teachers, they play tricks to get rid of them.
