On the spot, Helmut, an 85-year-old former paratrooper, manages a restaurant with his own methods: he goes behind everyone to criticize the slightest failure, criticizes his chef for not saving enough money, castigates his waitress for being too provocative when she wears a skirt, and interferes in the customers' conversations during service. As a result, the restaurant has a very bad reputation and the room is empty. However, this old man claims a family management of his restaurant and did not hesitate to give his chance to young people of the village to make his store work. Unfortunately, the benevolent grandfather has gradually turned into a terror for the staff. The arrival of Philippe will shake up Helmut's habits, especially since Ludovic, the young and talented chef, is on the verge of implosion. Another encounter that holds many surprises for Philippe Etchebest, our two-starred chef.
