It's Paris, 1962. Wealthy stockbroker Jean-Louis lives a staid and bourgeois existence with his perfectly-presented socialite wife. But when the family's maid abandons them, into the residence comes Maria, who is young, hardworking and - quelle horreur! - Spanish. Forming a friendship with the other maids on the 6th floor, Maria soon sweeps the conservative Jean-Louis up into their wild and fun-loving world.
