How do you turn a nice dinner into a real disaster? Nathalie and Jean-Luc, who call each other ‘chouchou’, are a model couple, a little silly and, to put it bluntly, really corny! This evening, they have invited Christophe, an old friend, to dinner, and he introduces them to his fiancée, Patricia. As they are coming out of one of their many arguments, Patricia, furious, decides to ruin the evening. Throughout the meal, she doesn't say a word. Intrigued, Nathalie and Jean-Luc think they're dealing with a stranger, and Patricia can't resist the pleasure of perpetuating the misunderstanding to shatter the evening... The evening is going to be one disaster after another, such is Nathalie and Jean-Luc's staggering naivety. Each situation leads to another, then another... until the final fireworks display. A comedy for everyone.
