Marguerite and Sofiane are a happily married couple trying to survive the chaos of parenting their teenage daughter Raphaelle. But their daily routine is disrupted when Marguerite’s ex-husband Fred shows up with an urgent, and utterly absurd request; they need to get divorced again.... but this time it’s to annul their Catholic marriage! Initially dismissive, Marguerite goes along with this yet doesn’t take the process seriously. After all, what could possibly go wrong? But her flippant attitude inadvertently sets off a chain reaction of bureaucratic absurdities. Before they know it, Marguerite, Sofiane, their teenage daughter Raphaelle, Cloe Fred’s new girlfriend, as well as Lea, Marguerite and Fred’s adult daughter, all embark on a crazy and highly unorthodox trip to the Vatican.
