Having first lost his wife then his job as a tweed tailor, Alex Ponttin has devised a novel way to keep himself in touch with society. He admits himself into people's homes, by pretending to be a relative or an official, and persuading his victims to give him a night's free board: He finds at first a lunch at the horrible couple Dumont, where a thief follows him for a robbery. Alex spent an evening in front of TV at Marie, mother of seven children. He runs from Marie to find an evening and a new bed at the home of charming but shy lesbian Caroline and her funny lover Gloria. To save her inheritance, Caroline - accused for her homosexuality by her horrible sister Catherine - tells her aunt Amélie, that Gloria is her secretary and Alex her lover. So Alex has to present himself nude in Caroline's bed. He saves Carolines inheritance. The police officers investigating the case are so terminally stupid that Alex has little chance of being arrested.

In the newspaper he has just founded, journalist Dolannes exposes all the wheeling and dealing and scandals that go on in his town.
