Philippe Etchebest was called to Marseille to help Sandrine, manager of a local restaurant that she runs with her sister Aline and her daughter-in-law Sabrina. As soon as he arrived, the chef quickly wondered where he had set foot... The establishment looked more like a beauty salon than a restaurant! And once at the table, nothing got better: the dishes offered turned out to be bland and uninteresting, but above all, the atmosphere between the two sisters is so electric that the meal quickly turned into a vaudeville! A situation that could have amused the chef if the future of the restaurant was not at stake. Between Sandrine, the boss who has completely given up, and her sister Aline, whose character and very familiar attitude will not fail to irritate the chef, Philippe Etchebest will have to redouble his efforts to try to save this restaurant that is on the verge of exploding!
