Thierry has not lived in Switzerland for many years, but now he has to return with his companion Sophie for his grandmother’s funeral. Unexpectedly, a large inheritance is offered to him on the condition that he appear capable, in the eyes of his uncles, of putting it to good use. However, as opposed to his brother and sister, he fails – and is even prepared to renounce his part – when his cousin Aloïs (who would like to get closer to Sophie) persuades him to try again…and to re-identify with Swiss values!
