Violette is broke and under threat of losing her children to care. Interviewed on TV she makes a heartfelt appeal about the importance of the family and not wanting to lose her children. Paul-André catches this interview and has the brilliant idea of helping Violette, by paying her debts and renting her family. His reason is that he wants to experience having a family before committing to have his own.
Having dispensed with the assurance that he is not looking for a relationship with Violette, a contract is drawn up for a three-month trial. Violette insists, however, that he lives with them. So we see Paul-André leaving his mansion to move into a house that has the appearance of a shanty. The children are not let in on the commercial arrangements and are told that he is the new boyfriend. Auguste, her young mixed-race son is happy to accept what he's told but the daughter, Lucie, older and as blonde as Auguste is dark, is not so easily persuaded. What follows is a typical semi-farce as the clash of cultures come together.
