Anne and Bob, a well-to-do American couple (Academy Award nominees Toni Collette and Harvey Keitel), have just moved to a beautiful manor house in romantic Paris. To impress their sophisticated friends, they decide to host a lavish dinner party, but must disguise their maid, Maria (Rossy de Palma) as a noblewoman to even out the number of guests. When the maid runs off with a wealthy guest (Michael Smiley), Anne must chase her around Paris to thwart the joyous and unexpected love affair.
