Young, Beautiful... Probably Rich

The story

Claudia, Rita, and Caterina are three friends who live in a conservative Italian town and lead seemingly neat and respectable married lives. One day, they are summoned to the notary public's office and learn that Anna, one of their peers in high school who got a bad name as a "whore" in the town because of them and was forced to leave is now dead. Furthermore, she had amassed a great fortune abroad and decided to bequeath it to the three. However, she has a strange condition: Claudia, Rita, and Caterina should cheat on their husbands within three days and provide photographic evidence or else the inheritance will be donated to the retirement home.
