Io Sono Mia on AllMovie

Giacinto (Michele Placido) has taken his wife Vanina (Stefania Sandrelli) along on his scuba-diving trip, mostly for the purpose of keeping his vacation cottage clean. At first, Vanina doesn't mind much, but she encounters Suna (Maria Schneider), a wealthy feminist, who encourages her to go out and meet the local people. When, after sex with a local teenaged boy, she discovers the possibility of orgasms, she wakes up to feminine power, and begins to assert herself. This film, based on Dacia Maraini's novel Donna in Guerra is reputedly the first Italian film made entirely by women.
