In dire need of money, best friends Rosalie and Kim decide to rob a bank. Along the way they pick up more partners in crime — and more problems.

With the cops and Ezéchiel determined to catch the bank thieves, Rosa's instructions not to spend any money go unheard as she tries to ditch the guns.

Fresh off a second heist, Rosa fears that a trail of evidence could lead back to her. Mayor Marionnaud uses a funfair to put the squeeze on Ezéchiel.
