Bahia Benmahmoud, a free-spirited young woman, has a particular way of seeing political engagement, as she doesn't hesitate to sleep with those who don't agree with her to convert them to her cause - which is a lot of people, as all right-leaning people are concerned. Generally, it works pretty well. Until the day she meets Arthur Martin, a discreet forty-something who doesn't like taking risks. She imagines that with a name like that, he's got to be slightly fascist. But names are deceitful and appearances deceiving.

Paris, in the early 1960s. Jean-Louis Joubert is a serious but uptight stockbroker, married to Suzanne, a starchy class-conscious woman and father of two arrogant teenage boys, currently in a boarding school. The affluent man lives a steady yet boring life. At least until, due to fortuitous circumstances, Maria, the charming new maid at the service of Jean-Louis' family, makes him discover the servants' quarter on the sixth floor of the luxury building he owns and lives in. There live a crowd of lively Spanish maids who will help Jean-Louis to open to a new civilization and a new approach of life. In their company - and more precisely in the company of beautiful Maria - Jean-Louis will gradually become another man, a better man.

After ratting out his Mafia cohorts, Giovanni Manzoni and his family enter the Witness Protection Program and relocate to a sleepy town in France. Despite the best efforts of their handler to keep them in line, Giovanni (now called Fred Blake), his wife and children can't help but resort to doing things the "family" way. However, their dependence on such old habits places everyone in danger from vengeful mobsters.
