Six Days a Week (1965)

Maria is a young beauty who is busy juggling three boyfriends (a count, a dentist and a student) at the same time. She manages this elaborate deception by impersonating her roommate Silvana who is a real life airline hostess. She lies to the count and the dentist about her flight schedules and her whereabouts so she can spend three days a week with each of them. She spends the remaining day of the week with the student who thinks she is a fellow student. One day surprising news of the real Silvana break out. Comedy and confusion ensure when Maria is forced to come up with a more elaborate scheme to cover her tracks and keep her boyfriends happy.
