Rosie Maldonne is outspoken and sexy. She’s also unemployed, and, with three children and a cat, life is a little tough. The four of them—well, five, if you count the cat—live in the South of France, in a run-down trailer near a vacant lot. They make do, living off her part-time waitressing job and a little help from the state. Rosie thinks things are finally turning around when she meets handsome police officer Jérôme—until she realizes that his appearance coincides with her friend Véro’s disappearance. Then, something even stranger happens: Rosie finds a package with a crazy amount of money in the trash can of a fast-food joint. With so much going on, Rosie has some big questions: Where is Véro? Is Jérôme too good to be true? Who put all that cash in the trash? And what happens when they want it back?
