An old and poor couple, Charles and Lucie, scrape by working as a concierge and an untalented antique dealer, respectively. But one day, their dreary daily routine is disrupted by the surprising news that they have inherited a luxurious house in the South of France.

In this whimsical French comedy, Cookie (aka Venus de Palma) is a tough, sweet little rich girl, and is rather smart, too. She's smart enough and charming enough to outwit her kidnappers by setting one against the other until they have all killed each other or died trying to prove thier worth to her.
