Modern comedy, full on childlike naivete and French elegance. Mother's pearls, father's Rolexes, even paintings off the walls of the house disappear without anyone noticing. Parisians Marianne and Abel (Laetitia Casta and Louis Garrel who are a family in real life too) get a slight shock - their youthful maximalist son Joseph sells the family's possessions to sponsor a secret project to save the planet. Truly, humor and optimism will save the world!
