It's in Paris, during the 1880's. The woman is Madame Loisel and the man is Mr.Loisel.
Mr. and Madame Loisel got invited to a party. Madame Loisel doesn't want to go because she doesn't have jewelry or a dress to go to the party.
Madame Loisel goes to her friend since Madame Forestier to borrow a pearl necklace from her.
Madame Loisel runs away from the party because she doesn't want to look poor in front of the people. When she runs the necklace falls off her neck and she loses it.
When Madame Loisel finds out that she lost the necklace she buys a new and replaces it. For the next 10 years Madame and Mr. Loisel have been working paying it off and end up in the lower class.
Madame Loisel goes to Madame Forestier to go tell her that she had lost the pearl necklace 10 years ago. When Madame Loisel told Madame Forestier, Madame Forestier told Madame Loisel that the pearl necklace was fake and Madame Loisel had bought a real pearl necklace to replace the fake one.
