Mathias Gold is a down-on-his-luck New Yorker who inherits a Parisian condo from his estranged father. However when he arrives in France to promote the huge domicile, he is shocked to find a live-in tenant who will not be ready to budge. His condo is a viager—an historical French actual property system with advanced guidelines pertaining to its resale—and the feisty Englishwoman Mathilde Girard, who has lived within the condo together with her daughter Chloé for a few years, can by contract gather month-to-month funds from Mathias till her demise.
