Spaak plays a female lothario who disguises herself as her roommate so she can carry on with various lovers. Since her roommate is a stewardess, this makes things all the easier. Salerno, an official of the Vatican, is one lover. Another is Michel, a Roman dentist. She meets with each man
three days a week, reserving the final day for Miranda, a man who knew Spaak when they were both students. Naturally, the trio finds out what's going on, but somehow Spaak convinces each man that he's the only guy for her.
