La Difficulté d'être infidèle

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.

Three young men - Jacques, Pierre, and Michel - share an apartment in Paris, and have many girlfriends and parties. Once, during a party, a friend of Jacques' tells him he has a quite compromising package to deliver, and asks him if he can leave it discreetly at their place. Jacques agrees and, as he works as a steward, flies away for a one-month trip in Japan, telling Pierre and Michel about the package. Then, one of Jacques' former girlfriends drops a baby before their door, making Pierre and Michel believing it is the package they are waiting for. Their lives are then completely changed.

Alexandre, a young and honest farmer, is oppressed by an authoritarian wife, who makes him work like a dog. When she dies in a car crash, he decides to stay in bed, absolutely free and inactive. Just a dog is occupied to carry food and newspapers to him.

Chronic serial womanizer Stephane Margelle drops his wife Sophie off at the airport so she can go away for Easter weekend. He immediately picks up beautiful young Julie, who has just had a fight with her married boyfriend. He gets her back to his apartment and is preparing for a sexy weekend, when his wife suddenly returns home. He makes up a bizarre, on-the-spot, spur-of-the-moment story that the gorgeous girl is actually his long-lost daughter. Julie plays along, but this leads to a whole series of increasingly ridiculous lies and comical situations (such as when her real mother shows up).
