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 realises 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?
