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.

Fred, a raffish safe blower, takes refuge in the Paris Metro after being chased by the henchmen of a shady businessman from whom he has just stolen some documents. While hiding out in the back rooms and conduits of the Metro, Fred encounters a subterranean society of eccentric characters and petty criminals.

“Traveling is not just going places, but meeting people, remarks a character in Michèle Rosier's refreshing human comedy. 18 people board a tour bus to Mont-Saint-Michel, eager and jittery — cameras aimed, desires out of focus. The motley crew includes a maturing maid mad to marry, a discreet Irishman, a pompous bourgeois, and a mysterious lady in Renaissance attire who looks as though she's lost her castle.No matches made in heaven here; in fact, the characters seem bent on driving each other crazy before the tour's end.When the bus is attacked by highway thieves, and its occupants divested of jewels and money, the misadventure makes them accomplice ... a kind of spell is cast on these mere mortals, shaken from their moorings, who quit their banality and take off from the big bus into another space, outward bound.” — Joan Dupont
