Paulette and her late husband had a brasserie. Now the xenophobic old lady lives alone in a banlieue and her pension is too small to get along. In the course of a Sequestration (law) most of her furniture and also her TV set are seized. Moreover, the landline is cut off because of overdue bills. Paulette is desperate to earn money somehow and she hears there is much money to be made in dealing cannabis. She visits a known criminal named Vito in her area and asks him for work. He commissions her eventually to sell his cannabis. Yet the other dealers don't put up with her unexpected success. They beat her up and rob her. Again she is desperate because she has to deliver a certain amount of money to Vito. Instead of just distributing sheer cannabis she starts to sell cakes and biscuits spiced with cannabis. Soon there is a huge demand for her elaborate pastries. Vito's boss gets enthusiastic about her success and plans to sell her biscuits to pupils. When she refuses to support this idea, the villain kidnaps Paulette's grandson. She starts a spectacular attempt to free him but in the end it is her son-in-law Ousmane who saves the day. Finally she leaves France and opens a cannabis coffee shop in Amsterdam, hereby becoming herself the kind of person she used to dislike: an emigrant.
