Bienvenue en Suisse

Thierry, an ethnologist specializing in the Sami people, travels to his native Switzerland with his partner, Sophie, to attend his grandmother's funeral. There he reunites with his family and discovers that he has inherited two million Swiss francs, but that in order to obtain it, he will have to pretend to adapt to the Swiss values and lifestyle that he had rejected. To do so, he agrees to undergo a sort of crash course provided by his Swiss cousin Aloïs, who seems to have his eye on Sophie.
