Industrialist Stéphane is getting a bit long in the tooth, but is still an incredibly charming man. When his wife Sophie goes away for the Easter weekend, he meets the attractive Julie by chance. The old philanderer takes her home with him to seduce the young lady. Due to an unforeseen strike, his wife Sophie is unable to fly out as planned and suddenly appears on the scene. Out of necessity, Stéphane unceremoniously introduces Julie as his daughter...

They live among doilies and all kinds of bric-a-brac, the two prissy old ladies Carter, and try to make the best of their pensioner's existence. For example, in a shopping game where they keep a whole army of sales clerks in suspense, only to end up buying nothing. A computer error provides the two with membership cards for the international service club, enabling them to make cashless payments. They end up with multi-digit dollar debts and a turbulent court case.
